Ashcroft 662876125593 Pressure Gauge 0-30 Psi 1.5 in Dial

Product Description

The ASHCROFT 662876125593 is a commercial-grade analog pressure gauge designed for monitoring system pressure in a wide range of plumbing, HVAC, and industrial service applications. It reads 0 to 30 psi through a 1.5-inch dial with 3-2-3% of scale accuracy, giving technicians a reliable visual reference for low-pressure systems. The bourdon tube is bronze, the case is steel, and the lens is polycarbonate. The gauge connects via a 1/8-inch NPT center back mount fitting, making it straightforward to thread into standard gauge ports without additional adapters. Licensed trades and service professionals install this gauge as a direct service or replacement component.

This gauge is suited for residential and light commercial applications where a compact 1.5-inch dial fits tight panel or manifold installations. The center back mount configuration is common on pressure taps, test ports, and equipment panels in HVAC, plumbing, and refrigeration service work. Its 0 to 30 psi range covers typical low-pressure monitoring needs such as water supply lines, pneumatic controls, and gas appliance service points. The CRN standard listing supports use in Canadian-registered pressure vessel applications where required by local code.

Installation Notes

Installation is typically performed by a licensed plumber, HVAC technician, or pipefitter. Shut off and depressurize the system completely before removing any existing gauge or fitting. Apply thread sealant or PTFE tape to the NPT threads per local code and the fitting manufacturer guidance. Do not over-tighten the 1/8-inch NPT connection, as the small thread size is susceptible to cracking the fitting body.
