Back
Back-up rings are essential for maintaining the integrity of your sealing system under high-pressure conditions. Designed to pair with O-rings, these rings act as a support barrier, preventing O-rings from extruding into clearance gaps. This extrusion can lead to seal failure, especially in applications with elevated pressures or temperatures.
HydraPak back-up rings come in several geometries and materials, from high-durometer nitrile to filled PTFE. This versatility provides compatibility with a wide range of O-ring applications, increasing sealing performance. Whether your application is static or dynamic, HydraPak’s back-up rings offer superior resistance to thermal and mechanical stress, minimizing downtime and extending the lifespan of your seals.
