Product Questions & Answers

what material is this o-ring made from, urethane or something else?

Question by: Lee P on Jan 21, 2026, 6:40 AM

Urethane is correct. The T420 designation on this LOMAR o-ring refers to the urethane compound used in its construction. Urethane o-rings generally hold up well in hydraulic applications where you need decent wear resistance and flexibility across a reasonable range of conditions.
