Question by: Stan E on Aug 15, 2025, 8:48 PM
What exactly does this retainer ring do in my hydraulic system?
Answer by: Customer Support on Aug 17, 2025, 6:19 AM
This backup ring is designed to keep your seals from squeezing out of place when the pressure spikes or when things are moving around a lot. It's there to support the O-rings and keep everything tight.
