A 5KG LPG gas cylinder is a compact refillable pressure vessel designed to store approximately 5 kilograms of liquefied petroleum gas (LPG) for cooking, heating, catering, and selected industrial applications. In practice, the cylinder’s external dimensions, tare weight, valve type, working pressure, and certification depend on the country, standard, and manufacturer. I recommend treating “5KG” as the nominal LPG filling quantity rather than a universal cylinder size. Before placing an order, buyers should confirm the applicable standard, connection, test requirements, quantity, delivery destination, and whether the quotation includes valves, painting, packaging, and transport documentation.
This guide is intended for LPG distributors, fuel retailers, catering-equipment suppliers, camping-equipment wholesalers, property developers, and industrial buyers sourcing 5KG LPG cylinders in volume. It is also useful for importers comparing quotations from different manufacturers. I focus on practical selection points rather than presenting one universal specification, because LPG cylinder requirements vary significantly by market and regulatory authority.
A buyer should use this information to prepare a technical inquiry, compare like-for-like offers, and identify questions that must be answered before production. A product photograph alone is not sufficient evidence of compatibility or compliance. The final specification should always be confirmed against the destination country’s legal requirements and the supplier’s approved technical documents.
A 5KG LPG gas cylinder is a portable or semi-portable steel or composite container intended to hold LPG in liquid form under pressure. “5KG” normally refers to the nominal mass of LPG charged into the cylinder, while the empty cylinder has an additional tare weight. A filled unit therefore weighs more than 5 kilograms, and the exact total depends on cylinder construction, valve, collar, foot ring, and surface treatment.
LPG is stored mainly as a liquid, with vapor occupying the space above the liquid. For this reason, a cylinder must not be filled completely with liquid LPG. The permitted filling ratio, valve arrangement, inspection interval, and handling rules must be determined by the applicable local regulations and cylinder standard rather than by a general online recommendation.
There is no single worldwide dimension for a 5KG LPG cylinder. A steel model may commonly have a body diameter in the approximate range of 250–310 millimeters and an overall height of roughly 400–550 millimeters, but these figures are indicative only and can change with the design, valve protection, foot ring, and required water capacity. A 5KG LPG filling quantity is approximately 11.0 pounds, using 1 kilogram = 2.20462 pounds. I recommend requesting a dimensioned drawing before designing storage racks, cages, vending spaces, or transport packaging.
| Item | What It Means | Typical Buyer Question |
|---|---|---|
| Nominal fill | Approximately 5KG of LPG | Is the quotation based on net LPG mass or cylinder tare? |
| Tare weight | Weight of the empty cylinder and fitted components | What is the guaranteed tare-weight tolerance? |
| Water capacity | Internal volume used for design and certification | What water capacity is shown on the approved drawing? |
| Overall dimensions | Height, body diameter, valve clearance, and base footprint | Will the cylinder fit the intended cabinet or appliance? |
| Valve connection | The interface between cylinder, regulator, and hose assembly | Does it match the destination market’s regulator system? |
As a safety reference, the U.S. Occupational Safety and Health Administration explains that LPG containers require suitable design, handling, and storage controls, while the relevant construction and use requirements may depend on the jurisdiction. The U.S. Department of Transportation also regulates certain transportable cylinders and pressure receptacles through its hazardous-materials framework. These references demonstrate why a buyer should confirm local compliance instead of relying only on nominal capacity. OSHA 29 CFR 1910.110 and U.S. eCFR hazardous-materials regulations are useful starting points for applicable markets.
A 5KG cylinder can suit compact kitchens, small households, temporary accommodation, and locations where storage space is limited. The actual service duration depends on burner power, operating hours, appliance efficiency, ambient conditions, and the LPG composition. For example, a 2-kilowatt burner consumes fuel at a different rate from a 4-kilowatt burner, so buyers should estimate demand from the appliance’s stated consumption rather than assume a fixed number of days.
Small restaurants, food stalls, mobile kitchens, and event caterers may select 5KG cylinders where portability and frequent exchange are more important than maximum runtime. Buyers should check whether the operation requires one cylinder or a duty-and-standby pair. The connection system, ventilation, separation from ignition sources, and local fire-safety rules are especially important in commercial settings.
A 5KG format may be practical for camping equipment, outdoor cooking, and temporary heating where a larger cylinder would be difficult to move. However, outdoor suitability does not automatically mean that a cylinder can be used inside a vehicle, tent, or enclosed room. I recommend matching the cylinder, regulator, hose, and appliance as one approved system and following the appliance manufacturer’s instructions.
Some service contractors and small workshops use compact LPG cylinders for approved heating or process equipment. This application requires particular attention to gas withdrawal rate, regulator capacity, cylinder orientation, and ventilation. If the equipment has high continuous consumption, a 5KG cylinder may be inconvenient even when its nominal capacity appears sufficient.
Welded carbon-steel cylinders are widely used because steel provides established pressure-vessel manufacturing methods and a durable structure. Common components include a welded cylinder body, valve guard or collar, foot ring, service valve, and protective coating. Their disadvantages can include higher empty weight and susceptibility to external corrosion when coating or storage conditions are poor.
Composite cylinders may reduce handling weight and can offer different corrosion characteristics, but they require product-specific approval, compatible filling infrastructure, and careful verification of service life and inspection requirements. Their purchase price may also differ from that of steel cylinders. I would not substitute a composite design for a steel specification without confirming acceptance by the local authority, filling station, distributor, and end-user equipment supplier.
ISO 22991 addresses transportable refillable welded steel gas cylinders and includes design and manufacturing considerations for cylinders in its scope. EN 1442 is another important reference used in some markets for transportable refillable welded steel LPG cylinders. Neither reference should be assumed to replace local approval, but both are useful when discussing technical requirements with a manufacturer. ISO 22991 information from ISO and the applicable national adoption of EN 1442 should be reviewed during specification preparation.

A professional quotation should contain more than the words “5KG LPG cylinder.” I recommend preparing a specification sheet that separates performance, compliance, dimensions, and commercial requirements. This reduces the risk of receiving products that have the correct nominal capacity but the wrong valve, marking system, or approval route.
| Specification Area | Information to Request |
|---|---|
| Capacity | Nominal LPG fill of 5KG, water capacity, and allowable filling ratio |
| Pressure | Design pressure, test pressure, working temperature range, and applicable standard |
| Dimensions | Body diameter, total height, base diameter, valve height, and drawing tolerance |
| Material | Steel grade or composite construction, wall thickness, weld process, and finish |
| Valve and accessories | Valve model, thread or connection, regulator compatibility, cap, and safety devices |
| Inspection | Inspection method, test records, marking, traceability, and requalification requirements |
| Packaging | Individual protection, pallet arrangement, container loading plan, and export labels |
Start with the country of import, the intended filling station, and the final application. The destination determines which construction standard, marking method, valve connection, transport rule, and inspection system may apply. A cylinder accepted in one market may not be accepted by a filling operator in another market even if both products are labeled 5KG.
List the connected appliances and their gas consumption, normally expressed in kilograms per hour, grams per hour, megajoules per hour, or another manufacturer-stated unit. A 5KG cylinder is not automatically suitable for high-demand equipment because vaporization capacity and operating temperature can affect performance. If continuous demand is high, ask the supplier or gas-equipment engineer whether multiple cylinders, a larger cylinder, or a manifold system is more appropriate.
Confirm the valve outlet, regulator inlet, hose connection, and appliance pressure as a complete set. Do not select a valve solely because it appears visually similar to an existing component. I recommend sending a reference drawing, sample valve, or clear technical code to the supplier and requesting written confirmation before production.
Ask for the applicable standard, manufacturing scope, inspection plan, test documentation, marking layout, and traceability method. Depending on the market, buyers may need certificates or documents from recognized inspection bodies, customs declarations, transport documentation, or local registration. The supplier should identify which documents are included in the offer and which must be arranged by the importer.
Before mass production, approve the cylinder drawing, valve specification, artwork, color, marking, packaging, and pallet configuration. A sample review is particularly valuable when the cylinders must fit an existing cabinet, weighing system, filling line, or delivery vehicle. For repeat orders, retain the approved revision and define a change-control process.
The price of a 5KG LPG gas cylinder cannot be stated responsibly as one fixed figure because steel prices, valve selection, certification, quantity, surface finish, packaging, exchange rates, and freight can materially change the landed cost. A low factory price may exclude the valve, inspection, export packaging, or destination-specific documentation. I recommend comparing the total delivered cost rather than comparing only the unit price.
Minimum order quantity (MOQ) depends on the production schedule, cylinder design, painting requirements, valve procurement, and packaging method. Standard components may support a lower MOQ than a customized valve, special color, private label, or destination-specific marking. Lead time should be divided into drawing approval, material and valve preparation, manufacturing, inspection, packaging, and shipping so that the purchasing team can identify the real project schedule.
| Cost Driver | Potential Effect on Quotation |
|---|---|
| Steel or composite material | Changes raw-material and empty-cylinder cost |
| Valve and safety components | Influences compatibility, availability, and unit price |
| Certification and inspection | May add testing, documentation, and third-party service charges |
| Customization | May affect tooling, MOQ, artwork, and production time |
| Packaging and freight | Influences container utilization and landed cost |
The World LPG Association publishes technical and safety resources that emphasize responsible LPG handling, distribution, and equipment management. Buyers can use these resources together with local authority requirements when developing procurement procedures and supplier questionnaires. World LPG Association publications provide useful industry context, but the importing authority remains the final reference for legal acceptance.
At Shuofang, I approach a 5KG LPG cylinder project as a specification-matching and supply-coordination task rather than a simple catalog purchase. We can discuss the required capacity, cylinder material, valve connection, dimensions, surface finish, markings, packaging, quantity, destination market, and documentation before preparing a quotation. The final offer should be based on the confirmed technical configuration, not only on the keyword “5KG.”
For an efficient inquiry, send the destination country, required quantity, preferred material, valve or regulator reference, application, target dimensions, applicable standard, branding requirements, packaging expectations, and desired delivery term. If some details are unknown, I can help organize the open items into a technical confirmation list. Any compliance, certification, or test-document requirement should be agreed in writing before production begins.
A 5KG LPG gas cylinder can be a practical option for compact cooking, catering, outdoor use, and selected light-duty applications when the fuel demand and local rules are suitable. The correct choice is determined by more than the 5KG label: buyers must confirm dimensions, water capacity, tare weight, pressure requirements, valve connection, inspection, certification, and logistics. I recommend obtaining a technical drawing and a complete commercial quotation before approving an order.
Your next step should be to prepare the destination-market and application details, then request a like-for-like quotation from a qualified supplier. Share the required quantity, preferred cylinder type, valve connection, standard, branding, packaging, and delivery destination with Shuofang for technical review. This process helps reduce compatibility risk and gives your purchasing team a clearer basis for comparing price, lead time, documentation, and long-term supply support.
