Common Questions
- Will this kit fit my valve?
- The SXI-HK-1A STEMEXTENTION fits 1/4", 3/8" and 1/2" sizes of Watts series LFFBV-3C M1 / LFFBVS-3C M1, design revision M1 only. Watts changed internal parts between revisions, so check the model stamped on your valve body or cover before ordering.
- What's included in this kit?

- Yes. This is the factory SXI-HK-1A STEMEXTENTION kit built with genuine Watts OEM components. Aftermarket parts can void your assembly approval and are commonly rejected by inspectors at annual test time.
