SD 131

Model DS 131 is a compact seal for high pressure sealing. It replaces an O-ring seal requiring a support 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 DS 131 collar provides sealing through its inside 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.
