Frequently Asked Questions

What is the Watts 3/8 SS 263A 100 300 pressure regulator used for?

The Watts 3/8 SS 263A 100 300 is a standard capacity water pressure regulator used to reduce and stabilize incoming water pressure in commercial and industrial plumbing systems. It protects downstream equipment from pressure surges and is suitable for applications requiring a stainless steel body for corrosion resistance.

What are the specifications of the Watts 3/8 SS 263A 100 300 pressure regulator?

This Watts pressure regulator has a 3/8 inch FNPT x FNPT connection, a stainless steel body, and an adjustable pressure range of 100 psi to 300 psi. The manufacturer part number is 3/8 SS 263A 100 300. It is designed for standard capacity water pressure regulation in industrial piping systems.

Where to buy the Watts 3/8 SS 263A 100 300 pressure regulator worldwide?

You can source the Watts 3/8 SS 263A 100 300 pressure regulator through 3G Electric, a global industrial equipment distributor. We handle full logistics, customs clearance, and delivery to worldwide destinations. Contact us for availability and lead time on this Watts regulator.

How to install the Watts 3/8 SS 263A 100 300 pressure regulator?

Install the Watts pressure regulator in the pipeline with the arrow on the body indicating flow direction. Use thread sealant on the FNPT connections and ensure the regulator is accessible for adjustment. Set the outlet pressure within the 100 to 300 psi range using the adjustment screw, then check for leaks before full operation.

Used in

Common applications for Watts
Industrial burner gas safety systems — Watts HF2000 filters with GF-series seal kits maintain clean, regulated gas supply to burner pilot and main flame controls
Commercial heating and boiler installations — Modular filter assemblies support preventive maintenance and component replacement without full system shutdown
Process gas delivery pipelines — DN25 through DN125 filter bodies accommodate varying flow rates and inlet pressures across manufacturing and chemical processes
Gas pressure regulation benches — Multi-stage Watts filter platforms integrate with pressure reducers and safety shutoff valves in test and calibration environments
Equipment retrofit and upgrade projects — Available connection sizes and seal kits enable adaptation of newer Watts components into legacy gas control systems
Planned maintenance and spare-parts inventory — Filter seal kits allow facilities to stock consumables in advance, reducing downtime during scheduled gas system servicing
