Ashcroft 601379A2LLLV/30 Pressure Gauge 6 in 0-30 Psi

Product Description

The ASHCROFT 601379A2LLLV/30 is a 6-inch analog pressure gauge designed for measuring system pressure in plumbing, HVAC, and industrial piping applications. It reads from 0 to 30 psi and connects via a lower-mount 1/4-inch NPT thread. The aluminum case keeps weight manageable at 3.13 pounds while the bronze wetted parts provide corrosion resistance against common system fluids. Accuracy is rated at 0.5% of scale, which is suitable for diagnostic and monitoring tasks where a reliable, readable gauge face is needed. This gauge is not liquid-filled, making it a straightforward mechanical pressure indicator for standard service environments.

This gauge fits typical service scenarios where a large, easy-to-read 6-inch dial face is preferred, such as boiler rooms, mechanical rooms, air compressor lines, water supply systems, and hydronic heating loops. The lower-mount configuration positions the connection at the base of the gauge body, which suits direct pipe or manifold installations where the gauge sits upright. It is installed by licensed plumbers, HVAC technicians, and pipefitters during both new construction and service work.

Key Features

• 6-inch dial diameter for clear, long-distance pressure readings
• 0 to 30 psi range suited for low-pressure plumbing and hydronic systems
• 0.5% of scale accuracy for reliable system monitoring
• Bronze wetted parts resist corrosion from common system fluids
• Aluminum case reduces overall gauge weight
• Non-liquid-filled analog design for standard, non-pulsating service

Compatibility

Designed as an OEM-style or replacement pressure gauge for low-pressure plumbing, HVAC, and hydronic piping systems that use a standard 1/4-inch NPT lower-mount connection.

Installation Notes

Installation is typically performed by a licensed plumber or HVAC technician. Shut down system pressure and relieve all residual pressure in the line before removing an existing gauge or installing this unit. Apply thread sealant tape or compound to the NPT threads per local plumbing code requirements. Do not use the gauge body as leverage when tightening — apply torque to the hex fitting only.
