Description
    Parker's H-seals are molded seals that can be used in as cast or machined grooves for face seal applications. They will fit traditional dovetail grooves or straight-walled grooves. If desired, Parker's H-seals can be self-retaining with the addition of retention ribs. The redundant sealing beads offer stability and resistance to twisting, which is particularly important with large profile seals. The small contact points of H-seal's generate high seal pressures, making them effective when mating surfaces are less than perfect.  The cross section can be used in a round profile or in custom-designed manifold systems. Parkers H-seal's cross sections can be refined to meet the specific seal load and/or system pressure requirements that your application demands.

    Applications:

    - Cover seals
    - Manifold seals
    - Perimeter seals
    - Face seals with low to high system pressures
