The 232 Series is a robust three-piece piston seal that consists of a profiled polyurethane seal ring 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 (H-PU)
Optimized for high running clearance
The 232 Series heavy-duty, three-piece piston seal features a robust profiled seal ring available in abrasion resistant polyurethane and two backup rings in high-strength thermoplastic.
