Question by: Lee J on Dec 30, 2025, 3:14 PM
what exactly is a backup ring kit used for in a hydraulic setup?
Answer by: Customer Support on Jan 1, 2026, 6:27 AM
Backup rings go in alongside primary seals to keep them from extruding into the gap between mating components under pressure. Without them, a soft seal can get pushed out of its groove over time, especially in higher-pressure systems, and you end up with leaks a lot sooner than you should. The urethane material in this kit holds up well against that kind of mechanical stress compared to softer elastomers.
