O-Ring Loaded Seal, Delta Shape
Our triangular o-ring loaded seal is available in one of six models, all of which are made up of a seal (with delta-shaped cross section) bonded to an o-ring. This sealing device is often used as a dynamic seal to fit around reciprocating piston rod in a pneumatic or hydraulic cylinder.
