DESCRIPTION

The PSC double-acting crown seal is a squeeze-type seal utilizing an o-ring as a loading spring to seal the static surface. The crowned sealing surface produces positive seal from vacuum to high pressure due to narrow single line seal contact area. The side legs act as an anti-extrusion device for the o-ring as well as add stability to the seal. Being bi-directional, PSC seals are also used in slow speed rotary services.

The shell is molded in polyurethane, ensuring flexibility for installation and performance at high/low pressures.

The PSC crown seal is directly interchangeable with corresponding T-seal, standard O-ring, O-ring w/Back-up (1 back-up – Intermediate Base; 2 back-ups – Wide Base), and PSM seal grooves.
