Weceleh 1/2" Gas Pressure Regulator for Natural Gas & Propane, 1/2" FPT with Brass Fittings, NG 4"w.c. / LPG 10"w.c.

The Weceleh GR-132 is a compact 1/2" gas pressure regulator that converts household natural gas or propane to stable outlet pressures (NG 4" w.c. / LPG 10" w.c.) and includes two brass fittings for reliable connections.

This regulator is built for residential and light-commercial gas appliances that require a precise low-pressure supply. It accepts a 1/2" gas pipe (13/16" outside diameter) and is factory-set for an inlet of 1/2 PSI with selectable outlet ranges for LPG and NG. The unit ships with two brass pipe fittings and is rated for a wide operating temperature range, making it suitable for most indoor installations when paired with correct piping and connectors.

How does this regulator control gas pressure for propane and natural gas?

The GR-132 uses an internal spring-and-diaphragm mechanism to reduce inlet pressure to a consistent low outlet pressure appropriate for cooktops, heaters, or other low-pressure appliances. Switching between LPG and NG simply involves using the device in the corresponding configuration; factory specifications list different outlet targets and flow rates for each gas type.

• Outlet pressure: LPG 10" w.c. (2.45–2.55 kPa); NG 4" w.c. (0.95–1.05 kPa)
• Inlet pressure: 1/2 PSI (nominal)
• Flow rates: LPG ~30 L/min; NG ~50 L/min under specified conditions

Which pipe sizes and threads are required for installation?

The regulator is built for 1/2" FPT gas pipe connections on both inlet and outlet; note that a 1/2" pipe commonly has a 13/16" outside diameter at the opening. The package includes two brass fittings—a reducing hex nipple and a male NPT adapter—to help adapt different threaded connections during installation.

• Thread type: 1/2" FPT on regulator inlet and outlet
• Opening measurement: measure near 13/16" to confirm compatibility
• Included fittings: reducing hex nipple and male NPT adapter in brass

What temperature and material performance should I expect?

The regulator body and included brass fittings are selected to resist corrosion and remain stable across a broad temperature range. Brass fittings provide ductility at high temperatures and low magnetic permeability, while the regulator itself operates safely within the specified environmental limits.

• Operating temperature range: -53°C to 121°C (-65°F to 250°F) for fittings
• Regulator operating range: approximately 30°F to 230°F for reliable performance
• Materials: brass fittings for corrosion resistance and regulator components sized for low-pressure gas

What installation cautions and operating notes should I follow?

Accurate measurement and correct pipe thread matching are essential: the product fits 1/2" interior-diameter pipe with an outside opening near 13/16". Always follow local codes and have a qualified technician install or verify connections, especially when converting between LPG and NG modes.

• Confirm inlet/outlet pipe diameter and thread type before purchasing
• Refer to provided dimensions and photos for fitment; measure the regulator opening at 13/16"
• Use a certified installer for gas line work and pressure testing

Who is this for? The Weceleh GR-132 regulator is intended for homeowners, appliance installers, and light-commercial operators who need a compact, dual-fuel pressure regulator for stoves, heaters, or similar low-pressure gas appliances. If you require a regulator sized for 1/2" gas piping with clear LPG and NG outlet settings, included brass adapters, and a durable build for typical indoor temperatures, this model is a practical choice. It is not a substitute for specialized industrial regulators or systems that require higher flow capacity or different pressure ranges; consult a professional when in doubt.
