The AP23 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.
The AP23 Series, four-piece piston seal is ideal for heavy duty sealing applications where pressure spiking can occur.
Typical applications include:
Specialty high-pressure cylinders
Various advancing and secondary cylinders
High pressure capability and wide temperature range
Excellent fluid compatibility including water-based fluids (H-PU)
Exceptional abrasion resistance
Highly extrusion resistant
Available in diameters up to 2000mm
