DMR Seals SS01 profile is a static O-Ring and Back-up Ring replacement seal. It is used where the installation of 2 back-up rings and an O-Ring are problematic and time consuming. The tapered sealing points allow easier installation into the mating hardware and the dual contact points offer a degree of sealing redundancy. It has excellent resistance to pulsating pressures and does not roll or twist in the groove due its excellent stability.
Commonly used on cartridge valves up to 400 Bar and higher through the correct choice of polyurethane material, it is an economical choice where O-Rings are routinely damaged at the installation stage and a more stable abrasion and tear resistant seal is required.
