Pressure gauge for welding regulators

The Miller-Smith Equipment GA135-03 is a pressure gauge designed for welding regulator applications. It measures from 0 to 60 psi with a secondary scale of 0 to 4 Bar. The gauge features a stainless steel case with brass and bronze wetted parts. It connects via a 1/4 inch MNPT bottom mount.

Accuracy and operating limits

The gauge delivers an accuracy of +/-3-2-3 percent across its range. Numbered graduations appear every 10 psi with the smallest graduation at 2 psi. The steel case is black and the unit is not liquid filled. It is not designed for panel mounting.

Basic gauge with no extras

No calibration certificate is included with this gauge. The package contains only the gauge itself without additional fittings or accessories. Buyers who need documented calibration or panel mounting capability should look elsewhere. There are no software components or digital features included.

Questions about this item

How do I install the GA135-03 gauge and what fitting mistake should I avoid?

Thread the 1/4 in MNPT bottom connection into the regulator port using a wrench on the steel case flats; do not tighten by turning the black painted case or the brass wetted parts will distort.

What maintenance will this pressure gauge need over time?

The dry stainless-steel case has no liquid fill to leak or refill; check the 2 psi smallest graduation against a known source periodically and replace the unit if the needle drifts beyond the ±3-2-3 % accuracy envelope.

What limit appears first when the gauge runs continuously at high pressure?

Sustained operation near the 60 psi top of the primary scale makes the ±3-2-3 % tolerance band reach its widest absolute error, so accuracy degrades before any mechanical fatigue occurs.
