Sta-Rite U9-226 O-Ring
The Sta-Rite U9-226 is a replacement o-ring, seated in a machined groove to seal a joint or a rotating shaft against water and air leaks. It is a small part, but a hardened or flattened o-ring is one of the most common reasons a pump weeps or loses its prime.
Inspect the groove the o-ring seats in for nicks or debris before installing the new one, since a damaged groove will cause the same leak even with a fresh o-ring. A light coat of silicone grease on the new o-ring eases assembly and protects it during installation.

Frequently Asked Questions
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.
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.
