Watts 0006988 Repair Kit
Service and maintain your Watts N55B series water pressure reducing valves with the Watts 0006988 Repair Kit (N55B-RK). This OEM-spec service kit is engineered for 1-1/4", 1-1/2", and 2" PRVs, providing a comprehensive solution to restore line pressure stability and prevent system creep. As a standard requirement for high-demand commercial and residential plumbing, the N55B-RK internal components allow technicians to overhaul the valve without removing the body from the line, significantly reducing labor hours and downtime.
The kit contains a heavy-duty EPDM diaphragm for superior chemical resistance and flexibility, alongside a stainless steel strainer to capture line debris that often leads to seat fouling. By replacing the seat/stem module, you ensure accurate downstream regulation and mitigate the risk of water hammer or thermal expansion damage. This lead-free compliant kit is the professional choice for extending the service life of Series N55B-M1 and LFN55B-M1 regulators while maintaining peak system efficiency.
Key Benefits
- Universal Size Compatibility: Fits 1-1/4", 1-1/2", and 2" Watts pressure reducing valves.
- Precision OEM Components: Includes high-grade EPDM diaphragm and stainless steel strainer for long-term reliability.
- System Protection: Restores the valve's ability to maintain a consistent 50 psi set point, protecting downstream fixtures and appliances.
- Simplified Maintenance: Features a modular seat and stem assembly for fast, tool-efficient installation.
- Lead-Free Design: Fully compliant with national lead-free standards for potable water applications.
Common Questions
How do I know if my Watts N55B valve needs a repair kit?
Internal wear usually manifests as "pressure creep," where downstream pressure slowly rises above the set point during no-flow conditions, or as visible leaking from the vent hole in the spring cage.
Is this kit compatible with the older N55B-M1 models?
Yes, the Watts 0006988 is the direct replacement kit for the N55B, N55B-M1, and lead-free LFN55B-M1 series in the 1-1/4" to 2" size range.
Does the kit include the replacement spring?
No, the N55B-RK focuses on the high-wear sealing components (diaphragm, seat, and strainer). If the adjustment spring is corroded or broken, it must be sourced separately.
