Product Introduction

SPGW piston seals combine a filled PTFE sealing ring, an NBR elastomer energizer, and PA or POM backup rings for double-acting sealing in high-pressure, heavy-duty hydraulic cylinders. They offer reliable dynamic and static sealing, low starting and running friction, and good wear resistance. The backup rings improve extrusion resistance and allow larger extrusion clearances. Smooth starting with reduced stick-slip helps maintain stable reciprocating motion. Featuring a simple groove design, SPGW seals are suitable for long-stroke applications in excavators, construction machinery, and heavy-duty hydraulic equipment.
