235 Series: Piston Seal – Compression – AE Ring
The 235 Series is designed for compact piston applications where space is restricted.
235 Series
The 235 Series is designed for compact piston applications where space is restricted. It consists of a profiled energizer, a polyurethane seal element and two L-shaped anti-extrusion rings that also function as bushings. It is designed for double-acting cylinders in heavy-duty applications subject to severe pressure spikes coupled with high running clearance.
