9K Backup Ring
- Improve MTBR by Preventing Extrusion Under Pressure
Chesterton 9K Anti-Extrusion Rings, often referred to as back-up rings, have no intended sealing function. 9K provides protection to pressurized dynamic and static seals (including O-Rings) from extruding into equipment clearances while under pressure, thus protecting seal components from premature failure and prolonging their service life. Protection is provided by tight fit of the anti-extrusion rings in the seal groove to minimize the extrusion gap.
