Commercial Compound Gauge 30 to 0 to 30 psi

The Value Brand commercial compound gauge measures vacuum and pressure on a single 2 1/2 in dial. It covers a range from 30 inHg vacuum through zero to 30 psi. The ABS plastic case and acrylic lens protect the bronze bourdon tube and brass socket. The 1/4 in male NPT bottom connection suits panel or direct mounting in automotive and HVAC service work.

Upgrade from single-range gauges

Technicians who currently switch between separate vacuum and pressure gauges gain one instrument for evacuation and charging tasks. The +/-3-2-3 percent accuracy meets typical manifold-set requirements. The jump is worth it when a job demands both deep vacuum verification and low-side pressure reading without swapping tools or recalibrating.

Check connection and environment before ordering

Verify that the 1/4 in male NPT bottom port matches your manifold block or service hose fitting. Confirm the bronze sensor and brass socket are compatible with the refrigerant or fluid in use. The gauge carries no IP or NEMA rating and is not rated for hazardous locations, so it must be used in clean, dry, non-classified areas only.

Questions about this item

What size NPT thread does the 1/4 in bottom connection require?

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

Which way should the dial face when threading the brass socket into a panel?

Because the gauge is not panel-mountable and the connection is bottom-mounted, thread the brass socket in until the 2 1/2 in dial faces the operator for easy reading.

When should the bronze sensor and acrylic lens be inspected or replaced?

Check the bronze sensor and acrylic lens for cracks or fogging after any over-pressure event beyond 30 psi or if the +/-3-2-3 percent accuracy drifts.
