The GFS Rod Buffer Cap Seal is a single-acting O-Ring energized PTFE rod seal used in dynamic sealing applications. The seal is installed in closed grooves, including grooves to ISO 7425. The seal assembly offers low friction and eliminates the potential for stick-slip, which makes it well suited for high speed applications. The Buffer Cap seal can be used as a standalone rod seal, or in tandem with other rod seals. It is most commonly used as a pressure buffer to protect the primary rod seal from spikes in pressure. The Buffer Cap Seal has high wear resistance, low break out force, and extrusion resistance. This sealing assembly is supplied standard with an energizing FKM O-ring, other elastomers can be supplied upon request.
