Piston seals with PTFE slide rings
GH profiles (fig. 1) have a nitrile rubber (NBR) energizer, which is an O-ring as standard. Rectangular energizers are available on request. These profiles are suitable for pressures up to 400 bar (5 800 psi) in medium to heavy duty applications. GH profiles are available in metric (→ Size list [pdf]) and inch sizes (→ Size list [pdf]) and some metric sizes fit seal housings in accordance with ISO 7425-1:1988.
