LCP seals are double-acting piston seals with a PTFE slide ring, with polyamide anti-extrusion rings on both sides, and a T-shaped nitrile rubber energizer. The anti-extrusion rings provide improved high pressure performance by reducing the likelihood of gap extrusion. The anti-extrusion rings are split for easy installation and their locking design reduces assembly issues. The PTFE cap reduces friction and provides longer seal life.
