O Rings
O Rings are ring-shaped seals with circular cross-section that can be used in a huge number of applications.
Materials available include Nitrile (Buna), Viton, Silicone, EPDM, PTFE, Chloropene (Neoprene) and Polyurethane.
O Rings are able to accommodate a wide range of operating temperatures; they can also withstand most chemicals.V Rings
V Rings are ring-shaped seals with a non-circular cross-section. A-type and S-type seals are available with the letter representing the shape of the cross-section.Oil Seals
Available in a variety of types including R21 (rubber-covered), R4 (metal-cased), Standard (metal-cased leather), R23 (rubber-covered with dust lip), R5 (double-sprung) 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 oils 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.Mechanical Seals
Mechanical seals are available for many applications. A whole range is now available including bellows seals.
To help identify the seal you need, please supply manufacturer and manufacturer part number, shaft diameter and stationary housing diameter, stationary gasket type (O Ring or Cup), free length of seal, estimated working length when compressed and (for taper seal) LH or RH spring.Can't Find It?
