Sta-Rite U9-228A O-Ring

This is the U9-228A o-ring. Rubber o-rings harden and take a permanent flat set over years of heat cycling, and once that happens no amount of tightening will restore the seal.

An o-ring that has taken a flat set or developed a visible crack should be replaced rather than stretched back into shape; both are signs the rubber has hardened past the point of sealing reliably.

Frequently Asked Questions

Q: Can I substitute a generic o-ring from a hardware store?
Only if it matches the exact inside diameter, cross-section, and material of the original; a close-but-not-exact size will leak or fail early.

Q: How do I know if this o-ring needs replacing?
A weeping leak at the joint it seals, a flattened or cracked appearance, or simply having been in service for several years are all reasons to replace it during a rebuild.

Q: Should I grease the new o-ring before installing it?
A light coat of silicone-based grease makes assembly easier and helps protect the o-ring, but is not strictly required for it to seal.

Q: Will this fit a different pump in the same series?
Match the exact part number on the old o-ring rather than assuming similar-looking pumps share the same size.
