233 Series: Piston Seal – Compression – AE Ring
The 233 Series is designed for compact piston applications where space is restricted.
233 Series
The 233 Series is one of the most robust four-piece piston seals available on the market. It consists of a profiled energizer, a polyurethane seal element and two full-face, 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
