254 Series: Piston Seal – Compression – AE Ring
The 254 Series is one of the most robust four-piece piston seals available on the market.
254 Series
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.
