Ashcroft 82125 Pressure Gauge 0-30 Psi 2.5 in Dial Npt

Product Description

The ASHCROFT 82125 is a liquid-filled industrial pressure gauge designed for accurate pressure monitoring in mechanical and process systems. It features a 2.5-inch analog dial with a 0 to 30 psi range and delivers 1% of scale accuracy, making it suitable for applications that require consistent, reliable readings. The stainless steel case and polycarbonate lens provide durable protection in demanding environments. The liquid-filled design dampens vibration and reduces pointer flutter, extending the service life of the Bourdon tube. Licensed HVAC technicians, plumbers, and industrial service professionals typically install this gauge in piping systems, pressure vessels, and mechanical equipment rooms.

This gauge is suited for residential and commercial mechanical systems where a compact, back-mount pressure gauge is required. The center back mount configuration allows direct installation into panel or bulkhead-mounted piping. The 1/4-inch NPT thread connection is a common size across water, air, refrigerant, and gas service piping. Its IP54 and IP65/NEMA 4 ratings make it appropriate for both indoor and outdoor installations where moisture or washdown exposure is a concern.

Compatibility

Designed as an OEM-style replacement or new-installation gauge for industrial and mechanical piping systems requiring a 2.5-inch dial, 1/4-inch NPT center back mount pressure gauge in the 0 to 30 psi range.

Installation Notes

Installation is typically performed by a licensed plumber, pipefitter, or HVAC technician. Isolate and depressurize the system before removing or installing any pressure gauge. Apply thread sealant appropriate for the service media to the NPT threads before installation. Verify the pressure range of the installed gauge is compatible with the system operating pressure before returning the system to service.
