DMR KB20-IFS is a compact single acting internal pressure face seal designed for both low and high-pressure static applications.
The seal comprises a P-shaped sealing element with pressure activated anti-extrusion ring / back-up ring and is manufactured to fit tight against the outside diameter of the seal groove. The seal also has an anti-extrusion ring to ensure the sealing element is protected from extrusion when hardware clearances are large or pressures are high. The anti-extrusion rings can be manufactured from several durable materials allowing a superior resistance to extrusion.
The KB20-IFS can be manufactured to suit most internationally recognised O-Ring grooves in both metric and imperial sizes as well as non-standard sizes.
