Boshart PGC-30-30 2" Dry Vacuum/Pressure Gauge, 1/4" LM

Boshart PGC-30-30 2" Dry Vacuum/Pressure Gauge, 1/4" LM

The Boshart PGC-30-30 is a 2" dial dry vacuum/pressure gauge built for general-purpose plumbing and mechanical rough-in work where a technician needs a quick, reliable visual read of system pressure or vacuum. It features a 1/4" lower-mount (LM) connection for direct installation into a tee, gauge port, or manifold fitting, and it is calibrated across a 30-30 range, reading from 30 in. Hg of vacuum up to 30 psi of pressure. This makes it well suited for HVAC, hydronic, well, and general fluid-handling systems where both vacuum and low-pressure conditions need to be monitored on the same dial. As a dry gauge, it has no internal glycerin fill, keeping the unit lightweight and straightforward for standard indoor rough-in applications. This gauge is intended for general-purpose service only and is explicitly not rated for use with oxygen systems, so installers should route it to compatible water, air, or hydronic lines rather than oxygen service. The compact 2" dial size allows it to be mounted in tight mechanical rooms, on manifolds, or near pumps and compressors where panel space is limited but a readable gauge face is still required. The 1/4" LM connection threads directly into standard 1/4" NPT gauge ports common on tanks, manifolds, pump housings, and test tees, simplifying integration into existing rough-in plumbing and mechanical assemblies without adapters in most standard installations.

Key Features

• Dial Size: 2" face for clear, easy-to-read pressure and vacuum indication in tight mechanical spaces.
• Connection: 1/4" lower-mount (LM) fitting for direct threaded installation into gauge ports, tees, and manifolds.
• Range: Dry vacuum/pressure gauge calibrated 30-30, covering 30 in. Hg vacuum through 30 psi pressure on a single dial.
• General-Purpose Design: Suited for standard water, air, and hydronic rough-in applications; not for use with oxygen.
• Dry Case Construction: No glycerin fill, keeping the gauge lightweight and simple for typical indoor mechanical installs.
• Bulk Packaging: Supplied 100 ea per package for contractors and distributors stocking multiple units for rough-in and service work.
