PGK - OK Profile, Customized Piston seal High Pressure Split Cap

The OK profile is a bi-directional piston seal designed for heavy duty
hydraulic applications. Its durable, two-piece design installs easily onto
a solid piston without the necessity of auxiliary tools. When installed
into the bore, the diameter of the OK profile is compressed to close the
step cut in the cap to provide excellent, drift free sealing performance.
The glass-filled nylon sealing surface handles the toughest applications.
It will resist shock loads, wear, contamination, and will resist extrusion
or chipping when passing over cylinder ports. The rectangular nitrile
energizer ring ensures resistance to compression set to increase seal
