Oil seals are used to seal around a rotating shaft and keep an oil-based lubricant inside an axle, engine, etc. Grease seals are used to seal more viscous grease lubricants in rotary shaft applications. In simplest terms, an oil seal is a barrier with four functions; retaining lubricants or liquids, excluding contaminants, separating fluids, and confining pressure. These seals help to keep the machine running as smooth as possible. Oil seals from Custom Gasket Mfg. can be used for any type of machinery that seals hydraulic fluid; pumps, automotive, cylinder manufacturers and more.
Custom Gasket Mfg. provides rotary oil seals and shaft seals in a variety of styles, sizes, and materials to appropriately suit your application. Our selection of fluid sealing products are available in a comprehensive range of rubber polymers including Nitrile (NBR), Viton®, Fluorocarbon (FKM), Silicone (VMQ), Neoprene®, Chloroprene (CR), Ethylene Propylene (EPDM), Polyacrylic (ACM), Styrene Butadiene Rubber (SBR), Fluorosilicone (FVMQ), Polyurethane (AU/EU), Hydrogenated Nitrile (HNBR), and Methyl Vinyl Silicone (MVQ). Our oil seals are produced from the highest quality springs and cases made from carbon steel, stainless steel or FDA Approved stainless steel. All products are manufactured according to ASTM D standards. Custom Gasket Mfg. can supply custom oil and rotary shaft seals to your OEM drawings and specifications.
If you are uncertain of the oil seal style you require, please feel free to send us an actual sample of your seal and Custom Gasket Mfg. will reverse engineer the seal for you. We offer cost-effective alternatives to brand name seals and have been able to consistently provide our customers with premium quality seals at significant savings. The most common oil seals styles used are; TC, SC, TA, SA, TB, SB, and VC. Oil seal types TA, SA, TB, and SB all have bare steel on their OD widths. Custom Gasket Mfg. can process the widths in different options; ground OD, highly polished bright steel, coated OD and painted with a rubber to fill in small cracks in the OD housing. The other types of common seals have OD widths that are rubber covered.
Custom Gasket Mfg. provides V-Rings for shafts requiring a dynamic seal. They are flexible rubber seals that stretch-fit onto the shaft and rotate with the shaft against a counter face. The body of V seals rotates with the shaft and holds itself in position by its elastic fit around the shaft. Sealing is produced by the contact between the lip and the face. The V-Ring seal has good sealing action when the shaft is asymmetric and/or there is some misalignment. They are specifically designed to protect the primary seal from contaminants. They provide excellent protection against all types of liquid, grease, oil, dirt, and other foreign materials.
Custom Gasket Mfg. also offers V-Ring Sets which are used as piston seals. They consist of a top seal, three middle rings, and a bottom seal. We supply them in Nitrile / Buna-N (NBR), EPDM, and Viton®, and we are well tooled for common dimensions.
Custom Gasket Mfg. provides custom wiper seals. A wiper seal is an axial seal that prevents contamination while allowing a reciprocating shaft to pass through the seals inner bore. A wiper seals primary task is to prevent the corruption of particles in the hydraulic system. They are often used for eliminating fluid contamination and to prevent dirt from entering a reciprocating shaft mechanism. Wiper seals are typically used on hydraulic and pneumatic cylinders and telescopic suspension forks for motorcycles and bicycles. Wiper seals are also manufactured from over 15 polymers including: Nitrile / Buna-N (NBR), Fluorocarbon (Viton®, Fluorocarbon (FKM), Silicone (VMQ), Fluorosilicone (FVMQ), Polyurethane (AU/EU), Natural Rubber (NR), Ethylene Propylene (EPDM), Hydrogenated Nitrile Rubber (HNBR), Styrene Butadiene Rubber (SBR), Chloroprene (Neoprene®), Urethane, and Teflon®.
End caps are designed for applications where the shaft does not pass through the housing wall of the bore. The end cover provides protection for the bearings. The covers are designed to fit into housing bores for rotary shaft seals. They have the same tolerances as those for the O.D. of a seal. The inner housing is carbon steel and the outer seal is nitrile rubber. Industries that typically use end covers are gearbox, automotive, agricultural equipment, exercise equipment, trucks, buses and trailers.
Custom Gasket Mfg. specializes in providing high-quality custom oil and special seals for the gearbox industry. This industry uses End Caps VK, VK-HP (HP is high pressure), Gamma Rings RM and RO.
Custom Gaskets custom oil seals and shaft seals are currently used in the following industries.
We excel in gearbox related applications for the following industries:
