Based on the original PTFE cap seal design, the GFS Piston Cap Seal C is a compact O-ring energized PTFE bi-directional piston seal.  The Cap Seal C performs with anti-extrusion, low friction and low wear properties; and is an excellent choice for applications requiring a compact design. The Cap Seal C is recommended for linear reciprocating applications where the stroke length is at least twice that of the groove width.   This sealing assembly is supplied standard with an FKM energizing O-ring, other elastomers can be supplied upon request.
