DK 127

Model DK 127 is a compact seal for high pressure sealing. It replaces an O-ring seal requiring a back-up ring.
Compared to an O-ring, the design of the part allows larger extrusion grooves and, at the same working pressure, its deformation is smaller. The DK 127 O-ring provides sealing through its outer diameter.
- Same housing as an O-ring O-ring with anti-extrusion ring.
- High dimensional stability.
- Easy assembly.
Used for static sealing on cushioned cylinder heads.
It is usually machined in polyurethane formulations. See materials section.
