20 CD 70 O Ring Highlights:
(1) Flexibility and resilience;
(2) Appropriate mechanical strength, including expansion strength, elongation and tear strength.
(3) The performance is stable, it is not easy to swell in the medium, and the heat shrinkage effect (Joule effect) is small.
(4) Easy to process and maintain precise dimensions.
(5) Does not corrode the contact surface, does not contaminate the medium, etc.


O ring material including: NBR, FKM, VMQ, EPDM, CR, BU, PTFE, NR, etc
20 CD 70 O Ring Application Range:
O-rings are the most commonly used and widely available rubber sealing rings in the market. Various nations and organizations have developed o-ring sizing standards that are now used worldwide. Metric o-rings and custom size o-rings are often used when a standard o-ring size will not fit an application or existing hardware. X-rings and Square-rings Marco Rubber offers custom o-rings and non-standard o-rings in most materials with no tooling fees or setup fees. If you don't see the size you need listed in a standard or metric o-ring size chart then please contact us or request a quote.
