Harris 25GX Propane Regulator

The Harris 25GX is a medium-duty, single-stage cylinder regulator built for propane and propylene. It delivers a maximum outlet pressure of 50 psig and features a 2.75 inch gauge for clear pressure monitoring. The brass body has a chrome-plated finish for durability in workshop environments.

Upgrade from preset or fixed-output units

This regulator replaces non-adjustable or lower-capacity models when precise flame control is required up to 50 psig. The single-stage design provides a direct pressure drop from cylinder pressure with a maximum inlet gauge reading of 400 psig. The step is worth it when the application demands manual adjustment via the control knob rather than a factory-set output.

Suited for propane and propylene cutting or heating

It fits CGA 510 inlets with a female 0.825-14 NGO connection and supplies a male 9/16-18 UNF outlet. The fiber-reinforced neoprene diaphragm handles the specified gases in medium-duty cycles. Buyers needing higher outlet pressures, multi-stage regulation, or compatibility with other fuel gases should look at alternative configurations.

Questions about this item

What inlet thread does the 25GX regulator need to connect to a propane cylinder?

The inlet uses a CGA 510 female connection sized .825 In. -14, which threads directly onto standard propane or propylene cylinders.

What is the correct sequence for installing and pressurising this single-stage regulator?

Close the control knob fully, open the cylinder valve slowly to seat the diaphragm, then adjust the knob until the outlet gauge reads the desired pressure up to 50 psig.

Which parts of the 25GX should be inspected or replaced after extended propane service?

Check the fiber-reinforced neoprene diaphragm and the brass chrome-plated body seals for cracking or leakage; replace them if the outlet pressure drifts or gas escapes.
