Common Questions

Will this kit fit my valve?

The RK-25AUB-OR 2 fits the 2" size of Watts series LF25AUB / LFU5B. Kits are size- and series-specific, so match the model stamped on your valve body or cover before ordering.

What's included in this kit?

This is a o-ring — it carries the factory parts for that subassembly only, not a whole-valve rebuild. See the Watts spec sheet for the exact part breakdown.

Are these genuine Watts parts?

Yes. This is the factory RK-25AUB-OR 2 kit built with genuine Watts OEM components. Aftermarket parts can void your assembly approval and are commonly rejected by inspectors at annual test time.
