Stainless Steel Pressure Regulator 1/2 in

The Watts SS263AP is a stainless steel pressure regulator with 1/2 in inlet and outlet ports. It adjusts downstream pressure from 10 to 125 psi and withstands a maximum inlet pressure of 300 psi. The body measures 2 1/8 in length and 4 3/4 in height, and the gauge port is 1/4 in. It is rated for temperatures up to 140 Degrees F and uses Buna-N seals.

Commercial, Industrial and Residential Installers

This regulator suits plumbers and maintenance teams who need reliable pressure control on 1/2 in lines across commercial, industrial or residential sites. It is not intended for systems requiring a different pipe size, a pressure range outside 10 to 125 psi, or fluid temperatures above 140 Degrees F. Installers needing other materials or connection types should look elsewhere.

10 to 125 psi Adjustment with 300 psi Max Inlet

The unit comfortably handles supply pressures up to 300 psi while delivering a regulated output between 10 and 125 psi. It runs out of headroom when inlet pressure exceeds 300 psi or when the required outlet pressure falls below 10 psi or rises above 125 psi. Operating temperature must stay at or below 140 Degrees F for reliable seal performance.

Questions about this item

What piping do I need to connect the 1/2 in inlet and outlet on this SS263AP regulator?

The regulator has 1/2 in female NPT threads on both ends so you need matching 1/2 in male pipe nipples or fittings and thread sealant rated for 300 psi.

Will the Buna-N seals hold up if my supply line occasionally reaches 140 Degrees F?

Yes the Buna-N seals are rated to 140 Degrees F and the body is stainless steel so short temperature spikes within that limit are acceptable.

How can I verify the outlet pressure is actually set between 10 and 125 psi after installation?

Install a gauge in the 1/4 in gauge port and adjust the spring until the gauge reads your target pressure within the 10 to 125 psi range.
