Product Identity

The Value Brand commercial compound gauge measures vacuum and pressure from 30 inches of mercury to 30 psi on a 2 inch dial. It uses a 1/4 inch male NPT bottom connection and a 304 stainless steel case with an acrylic lens. The dry gauge carries a +/-3-2-3 percent accuracy rating and is not field fillable.

Who It Suits

Technicians who need a single instrument for both vacuum and positive pressure checks on refrigeration, HVAC or pneumatic systems will find the compound range convenient. The bottom mount suits panel or direct pipe installations where a rear connection would not fit. Buyers who require a liquid filled case for high vibration environments or a field fillable design for on site calibration should look at other models.

Build Integration

The 1/4 inch NPT thread connects directly to standard fittings without adapters. The 304 stainless steel case resists corrosion in damp plant areas while the white dial and black markings remain readable under workshop lighting. Because the gauge is dry and not IP rated, it should be mounted where moisture ingress is minimal and vibration levels are low.

Questions about this item

What thread size does my system need to accept the 1/4 in NPT connection?

The gauge has a 1/4 in male NPT process connection at the bottom, so the mating port must be a 1/4 in female NPT thread.

Will the 304 stainless steel case and acrylic lens resist corrosion from older steel pipework?

The case is 304 stainless steel and the lens is acrylic, both chosen for general chemical resistance; they will withstand typical condensate and mild contaminants found in legacy piping.

How do I confirm the +/-3-2-3 percent accuracy is holding after installation?

Apply a known reference pressure at zero, mid-scale and full-scale points; the needle should read within the stated tolerance at each point.
