High-performance materials, provide outstanding wear and extrusion-resistance properties as well as large range of temperature and media compatibility. The P11 has a proven design pedigree as a high-performance seal used in demanding applications.

The standard P11 seal face includes pressure notches, which makes the seal very responsive to changes in pressure or direction of travel. Used successfully for years in performance-critical applications in construction equipment, machine tools, material handling, agricultural equipment, and other industries, the P11 is a workhorse compact, double-acting, piston-sealing solution.

The seal’s design fits a variety of housing sizes, including ISO 7425-1 grooves, and is offered in a wide range of metric and inch options. Proper guidance is recommended for this seal in heavy-duty applications.

Double‑acting hydraulic cylinder piston sealing: Double‑acting, O‑ring energized, low‑friction piston seal designed for bidirectional reciprocating pistons; fits ISO 7425‑1 grooves, available in metric and inch sizes.

High & low pressure universal hydraulic systems: Rated up to 600bar; performs reliably in both high and low pressure systems. Pressure notches enable fast response to pressure changes and direction reversal with no stick‑slip.

Medium‑high speed reciprocating mechanisms: Max speed 4m/s; low friction, no stick‑slip, ideal for medium‑high speed applications such as injection molding machines, die casters, servo hydraulics, and high‑speed machine tools.

Wide temperature & multi‑fluid harsh environments: Operates from -45°C to 200°C; offers superior wear & extrusion resistance. Compatible with mineral oils, synthetic esters, water‑based fluids; not for phosphate esters; suitable for metallurgy, marine, offshore, and wind turbine equipment.

Heavy‑duty & performance‑critical machinery: Proven in construction equipment, machine tools, material handling, agricultural machinery and other performance‑critical, long‑life applications; recommended with guidance rings in heavy‑duty service.

Compact design cylinder applications: Compact structure ideal for cylinders with limited piston space where reliable sealing and easy installation are required.
