Marking

O-rings that we provide are marked according to a system which gives the inner diameter, cross-section diameter, material code and hardness.

Material

As a standard we offer o-rings made of NBR 70Sh nitrile rubber.
However in our offer you may find hardness types ranging from 30Sh to 90Sh and materials, such as NBR, FPM, EPDM, SIL, delivered also in required color on request. We are able to offer our customers ca. 250 different material mixtures.

Certificates

Since customers expectations seem to grow, we are able to supply “non-toxic” o-rings for such branches as for example food branch.
To each delivery we enclose suitable quality and material tests certificates upon request.
