The 254 Series is one of the most robust four-piece piston seals available on the market. It consists of a profiled energizer, a PTFE-filled seal element and two active anti-extrusion backup rings. It is designed for double-acting cylinders in heavy-duty applications subject to severe pressure spikes coupled with high running clearance.
Long service life under the harshest conditions
compatible with water-base fluids
Optimized for high running clearance
The 254 Series piston seal features a robust NBR elastomer, a seal cap in low-friction PTFE-filled and two backup rings in high-strength thermoplastic.
