GH piston seals

GH seals are double-acting piston seals (fig. 1) and 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 and inch sizes and some metric sizes fit seal housings in accordance with ISO 7425-1:1988. For additional information, refer to GH profile data below.
