MD-L piston seals

MD-L seals are double-acting piston seals (fig. 1) and have a nitrile rubber (NBR) sealing ring with thermoplastic polyester elastomer (TPC) anti-extrusion rings on both sides, which incorporate the polyacetal (POM) guide rings. The guide and anti-extrusion rings are split for easy installation. MD-L profiles are suitable for pressures up to 250 bar (3 625 psi) in medium duty applications and are available in metric sizes. Some sizes fit seal housings in accordance with ISO 6547:1981. For additional information, refer to MD-L profile data below.
