Camco Mfg 40055 Brass Water Pressure Regulator 40-50 Psi

Product Description

The CAMCO MFG 40055 is a brass water pressure regulator designed to maintain a safe, consistent operating pressure of 40 to 50 psi in residential and light commercial water supply systems. It reduces incoming line pressure to a preset range, protecting downstream fixtures, valves, and appliances from pressure spikes that can cause leaks or premature component failure. Compliant with current low-lead requirements, the 40055 is suited for potable water applications where material compliance is mandatory. Plumbers and water system technicians install this regulator as part of routine pressure management on incoming service lines.

The 40055 is used on residential and light commercial water supply lines where incoming pressure exceeds safe operating limits for the connected system. Typical installations include point-of-entry service line protection, RV and mobile home water supply connections, and irrigation system supply lines. The preset 40 to 50 psi output range suits most standard plumbing fixture and appliance pressure ratings without requiring field adjustment.

• Maintains output pressure at 40 to 50 psi for consistent system protection
• Brass construction provides durability and corrosion resistance in water supply service
• Compliant with low-lead requirements for use on potable water systems

• Sold in packages of 6, suitable for stocking or multi-unit jobs

Compatibility

Designed as an OEM-style replacement or new-installation water pressure regulator for residential and light commercial potable water supply applications requiring 40 to 50 psi regulated output.

Installation Notes

Installation should be performed by a licensed plumber in accordance with applicable local plumbing codes and IPC guidelines. Shut off the main water supply and relieve system pressure before removing any existing regulator or fittings. Ensure flow direction marked on the regulator body matches the direction of water flow in the supply line. Do not exceed the rated inlet pressure range specified for this regulator.
