PSM-439 93A; 70A Urethane Piston Seal | 6 1/2 in ID
Molded from 93 Shore A polyurethane with a 70 Shore A energizer, this seal utilizes the same groove dimensions as a standard o-ring or T-seal. One or two Style 575 back-up rings may be used for wider grooves. Extrusion resistant by design, this seal is also resistant to rolling and twisting. Installation is an easy two step snap-in procedure with no need to re-size before insertion into the bore. Piston diameter “I” dimensions are given for pistons without wear rings.
