Nitrile (NBR) O-rings
Readily available and cost effective o-rings
Viton® (FKM) O-rings
Viton® O Rings have a low compression set and have high temperature and chemical resistance.
EPDM O-rings
EPDM has excellent resistance to weathering and ozone, water and steam, with good performance in castor and some phosphate ester based fluids.
Silicone O-rings
Silicone has poor tensile strength, tear resistance and abrasion resistance Silicones possess excellent resistance to temperature extremes.
FEP Silicone / Viton Encapsulated O-rings
An encapsulated O-ring comprises an elastomer energising core, which has a seamless jacket made from fluoropolymer.
HNBR O-rings
Hydrogenated nitrile is a synthetic polymer that results from the hydrogenation of nitrile rubber (NBR).
Kalrez® (FFKM) O-rings
This material has outstanding chemical resistance and a temperature capability up to +350°C.
Ekraz O-rings
Ekraz parts have a virtually universal chemical resistance. Temperature Range -50°C to +315°C.
PTFE O-rings
PTFE is an extremely inert material and is unaffected by virtually every known chemical including almost all acids, alkalis and solvents.
PTFE Backup / Support O-rings
Back-up rings are used in conjunction with O-Ring for both static and dynamic sealing applications.
