Product Overview

The American Granby EILPG1002-4LNL is a liquid-filled pressure gauge for monitoring compatible well pump, pressure tank, and water-system operation from 0 to 100 PSI. A readable gauge helps a homeowner or service technician observe cut-in and cut-out behavior, compare actual system pressure with expected settings, and identify changes that may point to a pump, tank, switch, or plumbing issue.

The liquid fill helps steady the pointer where vibration or pressure pulsation could make a dry gauge harder to read. This model has a 2 in. dial, a clear lens, and a 1/4 in. male pipe-thread connection. Confirm the required pressure range, mounting clearance, thread size, and gauge orientation before installation.
