Watts 263A brass pressure regulator

The Watts 263A is a lead-free brass pressure regulator designed for commercial and residential plumbing systems. It controls downstream pressure between 1 and 25 psi with FNPT connections on both inlet and outlet.

Pressure adjustment range 1 to 25 psi

This single specification decides whether the part matches the system design. The regulator holds outlet pressure anywhere in that band while withstanding up to 300 psi inlet pressure and fluid temperatures up to 140 degrees F.

Quarter-inch FNPT ports fit standard pipe threads

The 1/4 in FNPT inlet and outlet thread directly into matching pipe fittings without adapters. A 1/4 in gauge port allows pressure monitoring. Buna-N seals and brass body suit potable water applications where lead-free compliance is required.

Questions about this item

What does the 1 to 25 psi adjustment range mean for my water system?

The regulator can be set to deliver any outlet pressure between 1 and 25 psi, protecting downstream fixtures from higher supply pressure.

How does the FNPT connection type limit installation options?

The 1/4 inch female NPT threads accept matching male NPT fittings; other thread standards will not seal without adapters.

What clearance does the 4 3/8 inch height and 2 1/8 inch length require?

Allow at least 4 3/8 inches vertical space and 2 1/8 inches horizontal run for the brass body and adjustment knob.
