Piston Seal TP Profile | Zatkoff

Description

Parker’s Piston T-seal is designed to retrofit O-rings in no back-up, single back-up and two back-up standard industrial reciprocating glands. Its compact design provides improved stability and extrusion resistance in dynamic fluid sealing applications. The flange or base of the T-seal forms a tight seal in the gland and supports the anti-extrusion back-up rings. When energized, the back-up rings bridge the extrusion gap to protect the rubber sealing element from extrusion and system contamination. The Piston T-seal eliminates the spiral or twisting failure that can occur when O-rings are used against a dynamic surface. Parker offers the Piston T-seal in a variety of elastomer and back-up ring compounds to cover a wide range of fluid compatibility, pressure and temperature.

The TP profile is sold only as an assembly (elastomer and back-up).
