Press-in-Place Seals and PIP Seals from Parker 

Press-in-place seals from Parker form efficient seals

Press-in-place seals from Parker design technology provide seal retention in the straight-wall of dove-tail grooves, and can offer good replacements for O-rings that won't seal properly.

Press-in-place and PIP seal design retention ribs help installation. Design retention and stabilizer ribs line the seal for ease of installation. Press-in-place and PIP seals offer small contact point design requiring less flange, and allowing for maximum sealing under minimal pressure.

The stability and retention ribs also prevent the seal from twisting and offering exceptional sealing properties with non-ideal mating surfaces.
