Global Industrial B2781353 Pressure Gauge 30 Psi

Product Description

The GLOBAL INDUSTRIAL B2781353 is a 4-inch dry pressure gauge rated to 30 psi with a 1/4-inch NPT lower-mount (LM) connection and a plastic case. It uses a standard Bourdon tube movement designed to provide consistent, readable pressure indication over extended service life in demanding environments. The plastic case keeps weight low and resists corrosion in non-aggressive environments. This gauge is a practical choice for contractors, maintenance technicians, and trade professionals who need a reliable, easy-to-read pressure indicator on a variety of fluid or gas systems where the measured media will not corrode brass internal components.

The B2781353 is suited for residential and light commercial applications including pneumatic systems, air compressors, pump discharge lines, and hydraulic circuits. The 4-inch dial face provides clear visibility at typical working distances, making it practical for panel-mount or inline installation in shops, mechanical rooms, and job-site equipment. It is a general-purpose gauge intended for systems where the process media is compatible with brass wetted parts.

Key Features

• 30 psi pressure range suitable for low-to-medium pressure pneumatic and pump applications
• 4-inch dial face for clear, at-a-distance readability
• 1/4-inch NPT lower-mount connection for direct inline or panel installation
• Plastic case reduces overall weight and resists incidental moisture exposure
• Brass-compatible wetted parts - not intended for media that corrodes brass
• Sold individually (quantity: 1 per package)

Compatibility

Designed as a general-purpose replacement or new-installation pressure gauge for pumps, air compressors, pneumatic systems, and hydraulic circuits where the process media does not corrode brass wetted parts.

Installation Notes

Installation is typically performed by a licensed plumber, pipefitter, or qualified mechanical technician. Depressurize and isolate the system completely before removing an existing gauge or installing this one. Apply thread sealant or PTFE tape to the NPT threads per the fitting manufacturer recommendation and applicable plumbing codes before making up the connection. Do not over-tighten the NPT fitting, as plastic case gauges are more susceptible to damage from excessive torque than steel-case units.
