Sealing elements that keep fluid or gas inside a joint, selected by compound and profile to match the media and temperature.
A seal is chosen by what it has to sit in, not by what it looks like. The same O ring size in the wrong compound swells, hardens or cracks within weeks. This category covers O rings and Y profile seals across the compound families that cover most industrial duty: NBR for general oil service, HNBR where it must take more heat, EPDM for water and steam, FKM for aggressive media, and FFKM for the hardest chemical conditions. Tell us the media, the temperature range and the groove, and we will recommend the compound.
Y Seals and Y O-rings
Y seals, also called Y-rings, are lip seals whose two lips are energised by the sealed pressure itself. The ra...

View Details →Seals swelling or hardening because the compound does not suit the media
Leaks returning after a rebuild because the replacement was matched on size only
O rings extruding from the groove under pressure
Long waits for a special compound size that no local stockist carries
Dynamic seals wearing quickly where a static profile was fitted
Compound recommended from the media temperature and pressure, not from size alone
Static and dynamic profiles distinguished so the right one is fitted
Groove dimensions checked against the seal to avoid extrusion
Non stocked sizes and compounds produced rather than substituted
Specification recorded so repeat orders arrive in the same compound
Tell us the media, the temperature range, the pressure and whether the seal is static or moving, and we will recommend one and explain why.
Yes. Send the dimensions or the groove drawing and we will confirm feasibility.
It varies with compound and size and is confirmed with the quotation.
It depends on compound availability and tooling and is stated in the quotation.
This depends on the compound and factory and is confirmed on request.
Send the capacity duty or drawing you need for rubber seals and o rings and we will match it to the factory that builds it and quote it in writing.
