PTFE Compression Packing

GFS Piston Seal profiles are designed and manufactured to optimize leakage control. Piston Seals offer sealing contact between the cylinder head and the cylinder bore, allowing pressure to build during stroke movement. GFS Piston Seal profiles are available as single acting (pressure from one side) or double acting (pressure from both sides). Available GFS Piston Seal profiles are available for purchase by selecting the profile image below or viewing all GFS Piston Seal profiles together here.

Different Piston Seal profiles offer distinct advantages depending on the sealing application. Temperature, Pressure, Stroke Speed and other environmental considerations would lead users to different profiles and materials. Primary Piston Seal materials are Polyurethane and PTFE blends.  Specific GFS Piston Seal materials are outlined below.

Optimizing Compression Packing performance can be a very complicated process.  If you require the input or design assistance of a GFS engineer for your application, please contact GFS here.
