1 1/2 in dial commercial gauge

The Value Brand commercial pressure gauge measures from 0 to 300 psi on a 1 1/2 in white dial housed in a 304 stainless steel case. A 1/8 in male NPT centre-back connection threads directly into test ports. The acrylic lens protects the dial face. This new instrument is built for technicians who need a straightforward pressure reading in hydraulic or pneumatic systems.

Replaces worn analogue gauges

Swap this gauge in when an existing unit shows drift beyond the stated +/-3-2-3 percent accuracy or when the lens has cracked. The 304 stainless steel case resists corrosion better than plated brass alternatives, extending service life in damp environments. The jump is worth it when the old gauge can no longer be calibrated or its connection threads are damaged.

Fits panel and inline mounts

The centre-back male NPT fitting suits panel cut-outs or direct pipe installation without extra adapters. Because the case is not field-fillable and has no liquid dampening, it keeps the build simple and avoids leak paths. The gauge needs no external power, freeing up wiring routes on crowded test rigs. It is not for applications requiring IP-rated sealing or vibration-damped movement.

Questions about this item

What thread size fits the 1/8 in NPT connection on this gauge?

The gauge uses a male 1/8 in NPT thread, so it mates with any standard female 1/8 in NPT port.

How do I install the gauge without damaging the 304 stainless steel case?

Apply thread sealant to the male NPT threads, then tighten with a wrench on the hexagonal wrench flats — never turn the case itself.

Will the acrylic lens need replacement if it yellows or cracks?

The lens is fixed in the case and is not field-replaceable; if it becomes damaged the entire gauge must be replaced.
