DESCRIPTION

O-rings are the most common and cost-effective sealing elements available. They seal over a wide range of pressure, temperature and tolerance. They are an excellent option where space limitations are a concern. And with proper hardware design, o-rings can seal a wide range of pressures from low vacuum up to several thousand PSI. O-rings are available in a wide range of elastomers as well as PTFE.

Ethylene Propylene Rubber (EPR, EPDM): EPR copolymer ethylene propylene and ethylene-propylene-diene rubber (EPDM) terpolymer are particularly useful when sealing phosphate-ester hydraulic fluids and in brake systems that use fluids having a glycol base.

EPR/EPDM o-rings are readily available in 70 and 90 durometer. Other durometers are available on request.
