The Grooved Piston Seal (GPS) is a three-piece assembly consisting of an elastomeric energizer, a filled PTFE grooved cap ring, and an elastomeric quad-ring. The seal combines low friction and positive sealing.
Grooved Piston Seals are available in inch and metric sizes.
• Low friction – no stick slip
• High strength precision machined PTFE cap ring
• Wide range of materials available for special applications
• Stable design prevents rolling
