Copeland EILPG1002-4LNL Liquid Pressure Gauge 0-100 Psi

Product Description

The COPELAND EILPG1002-4LNL is a glycerin-filled liquid pressure gauge designed for accurate pressure measurement in high-vibration environments. It features a black steel case, a phosphor bronze Bourdon tube, and a 2-inch dial face with a clear acrylic lens. The glycerin fill dampens needle movement caused by vibration or pressure pulsation, allowing for stable, readable measurements. The gauge reads from 0 to 100 psi and connects via a 1/4-inch lower MIP thread in a vertical orientation. It is installed by licensed HVAC technicians, plumbers, and refrigeration mechanics on systems where pressure monitoring is required.

This gauge is suited for residential and light commercial applications where system vibration would cause an unfilled gauge to give erratic readings. The vertical mount and lower MIP thread connection make it appropriate for inline piping, pump systems, compressor lines, and similar installations. The 2-inch dial provides a clear readout in tight equipment spaces. Its steel case and phosphor bronze internals hold up in demanding service conditions.

Key Features

• Glycerin-filled case dampens needle flutter in high-vibration applications
• Phosphor bronze Bourdon tube for corrosion resistance and accurate pressure response
• 0 to 100 psi pressure range with plus or minus 3-2-3 percent accuracy
• 2-inch dial face with clear acrylic lens for easy readout
• 1/4-inch lower MIP thread, vertical orientation for straightforward inline installation
• Black steel case construction for durability

Compatibility

Designed as an OEM-style replacement or service gauge for use on systems requiring a 1/4-inch lower MIP connection, glycerin-filled pressure measurement in the 0 to 100 psi range.

Installation Notes

This gauge is typically installed by licensed plumbers, HVAC technicians, or refrigeration mechanics. Shut down and depressurize the system completely before removing or installing any pressure gauge. Use appropriate thread sealant on the MIP connection and do not overtighten, as the steel case and bronze internals can be damaged by excessive torque. Verify the pressure range of the gauge is compatible with the system's operating and maximum pressure before placing it in service.
