DST 109

The support ring prevents extrusion of an elastomer seal for both static and dynamic service.
Model DST 109 is a non-metallic support ring, with a cross section and a concave cross section to better adapt to the O-ring contour. Depending on the working pressure, one or two rings can be installed on both sides of the elastomer seal.
- For all O-rings (inner and outer).
- High mechanical resistance.
- Ease of assembly.
