Seals & O Rings

A relatively low cost item, but vital to so many applications!

Transpower Drives stock a huge range of Seals and O Rings in both Metric and Imperial sizes, available off the shelf with no minimum order quantity!

Oil Seals

Are available in a variety of types including R21 (rubber-covered), R4 (metal-cased), Standard (metal-cased leather), R22 (double-lip, double-sprung, rubber-covered), R23 (rubber-covered with dust lip), R5 (double-lip, double-sprung, metal-cased) and R6 (metal-cased with dust lip).

Nitrile rubber provides the normal sealing medium but Viton tends to be used for high temperatures or chemical-handling applications.
Most oil seals are designed to handle 0.5 bar pressure, however, PTFE seals can hold pressures of up to 10 bar. Split seals can be used to avoid having to dismount heavy machinery.

O Rings

Materials available include Nitrile (Buna), Viton, Silicone, EPDM, PTFE, Chloroprene (Neoprene) and Polyurethane.
O Rings are able to accommodate a wide range of operating temperatures; they can also withstand most chemicals.
