PTFE Piston seals

Type OE (210 serie)

Operating conditions

Pressure:    ≤ 400 bar (600 bar, by reducing extrusion gap)

Temperature: -40°C...+200°C (depends on the O-Ring)

Speed:         ≤ 4 m/s

Materials

(1) Dynamic sealing part, Modified bronze PTFE (PO52)

(2) O-Ring, NBR-elastomer

Installation

One-piece piston (see installation guide)

Advantages

- Short assembled length.

- Minimal break-out and dynamic slide friction, no stick-slip phenomenon. Steady movement is guaranteed even at low velocities.

- High wear resistance

- High extrusion resistance

- Compatibility with nearly all media and temperatures due to the high chemical resistance of the rod sealing ring, and a wide selection of O-ring compounds.
