American Granby EILPG302-4LNL Liquid Gauge 30 Psi

Product Description

The AMERICAN GRANBY EILPG302-4LNL is a steel-body liquid gauge rated to 30 psi with a 2-inch dial face and a 1/4-inch lower-mount (LM) connection. Built for use in fluid systems that require reliable pressure monitoring, this gauge is designed for trade installation in plumbing, HVAC, and hydronic heating applications. The steel construction provides durability in typical service environments. The lower-mount connection simplifies inline installation where bottom-entry gauges are required. Licensed plumbers and HVAC technicians are the primary installers of this type of gauge.

This gauge is suited for residential and light commercial liquid systems where pressure readings up to 30 psi need to be monitored at a glance. The 2-inch dial provides a clear, readable display in confined mechanical spaces. The 1/4-inch lower-mount port is a standard thread configuration common in hydronic loops, boiler systems, water supply lines, and similar low-to-medium pressure plumbing circuits. The NL designation indicates a no-lead-compliant construction appropriate for potable water contact where local codes require it.

Key Features

• Steel body construction for durability in liquid service applications
• 30 psi pressure range for low-to-medium pressure system monitoring
• 2-inch dial face for clear readability in tight mechanical spaces
• 1/4-inch lower-mount (LM) connection for straightforward inline installation
• No-lead (NL) compliant construction suitable for potable water applications

Compatibility

Designed as an OEM-style replacement or direct-install gauge for residential and light commercial liquid pressure monitoring systems using a standard 1/4-inch lower-mount port configuration.

Installation Notes

Installation should be performed by a licensed plumber or qualified HVAC technician in accordance with applicable local plumbing codes and the International Plumbing Code (IPC). Shut off system pressure and relieve residual pressure in the line before removing or installing the gauge. Use an appropriate thread sealant rated for the system fluid on the 1/4-inch male threads. Do not over-tighten the connection, as excessive force can damage the gauge body or fitting threads.
