Value Collection 111CL25V30 Compound Gauge 30 Psi

Product Description

The VALUE COLLECTION 111CL25V30 is a compound pressure gauge designed to measure both positive pressure and vacuum in a single instrument. With a 2.5-inch analog dial and a pressure range of -30 inches Hg to 30 psi, it covers common low-pressure and vacuum applications found in HVAC, plumbing, and light industrial service. The ABS case houses brass wetted parts and a bronze Bourdon tube, delivering a 3-2-3 percent of scale accuracy across the full range. Installation is via a lower-mount 1/4-inch NPT threaded connection, making it straightforward to fit into standard gauge ports and test manifolds.

This gauge is well suited for residential and light commercial HVAC work, refrigeration service, plumbing pressure testing, and general fluid system monitoring where a compact, non-liquid-filled compound gauge is appropriate. The lower-mount configuration positions the dial face upright when the gauge is threaded into a bottom port or tee fitting, which is the most common orientation for panel and inline installations.

Key Features

• Compound range: -30 inches Hg vacuum to 30 psi positive pressure on a single dial
• 2.5-inch analog dial for clear reading at typical working distances
• 1/4-inch lower-mount NPT connection fits standard gauge ports and fittings
• Brass wetted parts and bronze Bourdon tube for compatibility with water, air, and common refrigerants
• ABS case construction — lightweight and resistant to common shop environments
• Non-liquid-filled design — no fill fluid concerns during installation or disposal

Compatibility

Designed as an OEM-style replacement or add-on gauge for systems requiring a lower-mount, 1/4-inch NPT compound gauge with a 2.5-inch dial and a 30 psi range.

Installation Notes

A licensed HVAC technician or plumber should install this gauge in accordance with applicable local codes and IFGC or IPC requirements for the system being serviced. Isolate and depressurize the system fully before threading the gauge into the port. Apply thread sealant or PTFE tape to the male NPT threads — do not overtighten, as the brass fitting can be damaged. Verify the gauge reads zero at atmospheric pressure before returning the system to service.
