Brass Water Pressure Regulator 10-35 psi

This brass regulator controls incoming water pressure between 10 and 35 psi for commercial and residential plumbing. It connects via 1 inch FNPT union fittings and handles a maximum supply pressure of 300 psi. The body withstands temperatures up to 160 degrees Fahrenheit. It meets ANSI A 112.26.2, ASSE 1003 and CSA B356 standards.

Suits Fixed Low-Pressure Systems

Installers needing a factory-set low-pressure range for irrigation, fixtures or equipment protection will find this range appropriate. Systems requiring adjustment above 35 psi or a different connection type should select another model. The lack of a gauge port means pressure verification requires an external fitting.

Union Connection Simplifies Installation

The FNPT union tailpiece allows the regulator body to be removed without cutting pipe, reducing service time. No pressure gauge, strainer or bypass valve is included in the package. The unit ships ready for direct installation on 1 inch piping.

Questions about this item

What pipe size and connection type must my existing plumbing have for this 1 in FNPT union regulator to thread on directly?

Your supply lines need 1 in pipe with female NPT threads so the union ends can screw on without adapters.

Will the brass body and 300 psi rating handle the pressure spikes from my older municipal supply?

Yes, the brass construction is rated for 300 psi maximum, well above typical municipal surges.

How can I verify the regulator is holding pressure in the 10 to 35 psi range after I install it?

Install a downstream gauge, open a fixture, and confirm the reading stays within the 10 to 35 psi adjustment window.
