Watts 0864945 Repair Kit

The Watts 0864945 Repair Kit is the professional-grade solution for servicing 1-1/2" 25AUB-RK water pressure reducing valves. This lead-free repair kit, officially designated as RK-LF25AUB-Z4, is engineered to restore factory-spec pressure regulation in high-demand plumbing systems. As a veteran-preferred direct replacement for 25AUB-RK-1 1/2, it addresses common failure points such as fluctuating downstream pressure and bypass leakage caused by mineral buildup or component fatigue.

This comprehensive kit includes a reinforced diaphragm, diaphragm liner, seat, disc, disc screw, and a full set of static seals: O-rings, union gaskets, strainer plug gaskets, and bottom plug gaskets. By replacing the internal trim and elastomers, you maintain the integrity of commercial and industrial water distribution networks without the labor-intensive requirement of a full valve body cut-out. The components are manufactured from heavy-duty materials to withstand industrial line pressures while ensuring compliance with safe drinking water standards.
