Watts 0354563 Kit

The Watts 0354563 (Model P60-M1-RK) is an essential pressure reducing valve repair kit engineered specifically for the Watts P60 miniature plastic water pressure regulator. Designed for high-performance in light commercial and OEM applications, this kit allows technicians to rebuild the 1/4 inch regulator body without replacing the entire unit. It features FDA grade elastomers, ensuring that all internal rubber components like the diaphragm assembly and seals remain compatible with potable water and deionized water applications. By utilizing 300 series stainless steel internals, this kit provides superior resistance to corrosion and scaling in demanding environments. Whether you are addressing a creeping outlet pressure issue or performing routine maintenance on a balanced piston design regulator, this kit provides the factory-spec parts required to restore precise downstream pressure control and maintain the system's high flow capacity. Professional installation ensures the corrosion-resistant thermoplastic body continues to operate within its original 300 psi maximum inlet pressure rating.

• Full Internal Overhaul: Includes the diaphragm assembly, stem assembly, diaphragm slip ring, and bottom plug o-ring for a complete rebuild.
• Enhanced Material Compatibility: Features Buna-N FDA elastomers and 300 series stainless steel components suitable for pure water and OEM systems.
• Cost-Effective Maintenance: Restores the function of the compact and lightweight P60 regulator without the need for plumbing reconfiguration.
• Accurate Regulation: Maintains the accurate flow performance required for precision machinery and general-purpose water regulation.
• Service Accessibility: Designed to work with the P60’s bottom clean-out plug for efficient field servicing.

What problems does the Watts 0354563 repair kit solve?
This kit is the primary solution for 1/4 inch P60 regulators experiencing internal leakage, failure to hold set pressure (pressure creep), or physical wear of the diaphragm and seals.

Is this kit compatible with deionized water systems?
Yes. Because the RK-P60 repair kit utilizes stainless steel and FDA-grade elastomers, it is specifically rated for use in deionized water applications where standard metals might fail.

How do I know if I need a P60-M1-RK or a full regulator replacement?
If the thermoplastic body is cracked or the inlet/outlet threads are stripped, a full replacement is necessary. However, if the body is intact but the pressure regulation is inconsistent, this 0354563 maintenance kit will restore full functionality.
