American Granby ilpg20025-4lnl 0-200 Psi Pressure Gauge

Product Description

The AMERICAN GRANBY ilpg20025-4lnl is a glycerin-filled, dial-type pressure gauge built for service in high-vibration and corrosive environments. It reads 0 to 200 psi across a 2.5-inch stainless steel dial face covered by a clear acrylic lens. The sensing element is a phosphor bronze Bourdon tube housed in a stainless steel case with a crimped stainless steel retaining ring. A lower-mount, 1/4-inch male threaded connection makes installation straightforward on most standard gauge ports. Licensed plumbers, HVAC technicians, and irrigation professionals are the typical installers for this type of instrument.

This gauge is rated for air and water applications and complies with NSF/ANSI 372 for lead-free construction, making it suitable for potable water systems as well as general HVAC and mechanical systems. The glycerin fill dampens needle oscillation caused by pressure spikes or continuous vibration, extending service life and preserving dial readability in demanding field conditions. It is available and packaged 50 units per carton, making it a practical choice for contractors stocking gauges for recurring service work.

Key Features

• Glycerin-filled case dampens needle movement in high-vibration service conditions
• Phosphor bronze Bourdon tube sensor element for reliable pressure response
• Stainless steel case and crimped retaining ring resist corrosion
• 2.5-inch dial face with clear acrylic lens for easy field reading

• NSF/ANSI 372 compliant lead-free construction for potable water compatibility

Compatibility

Rated for air and water service. Designed as a lead-free, liquid-filled replacement gauge for residential and commercial plumbing, HVAC, and irrigation systems requiring a 1/4-inch male lower-mount connection and a 0-200 psi range.

Installation Notes

Installation should be performed by a licensed plumber or qualified mechanical technician. Depressurize and isolate the system completely before removing any existing gauge or fitting. Apply thread sealant or PTFE tape to the 1/4-inch male threads per local plumbing code requirements. Do not overtighten the connection; use a wrench on the hex body, not the case, to avoid damaging the instrument.
