Ashcroft 662876143900 Pressure Gauge 0-15 Psi 3.5 in

Product Description

The ASHCROFT 662876143900 is a commercial-grade analog pressure gauge designed for industrial and mechanical system monitoring applications. It features a 3.5-inch steel case dial with a 0 to 15 psi range and delivers 3-2-3 percent of scale accuracy across the full measurement span. The Bourdon tube is bronze construction, and the lens is polycarbonate for durability and readability. The center back mount configuration with a 1/4-inch NPT threaded connection makes this gauge well-suited for panel mounting on piping systems. HVAC technicians, plumbers, and mechanical contractors install this type of gauge to monitor low-pressure fluid or gas systems.

This gauge is appropriate for residential and light commercial applications where monitoring pressures up to 15 psi is required. Typical installations include low-pressure gas lines, water supply systems, hydronic heating circuits, and compressed air monitoring points. The center back mount orientation allows the dial face to sit flush against a panel or bulkhead, keeping the gauge face visible and the piping connection concealed behind the mounting surface. The analog dial provides a clear local readout without requiring external power.

Installation Notes

Installation should be performed by a licensed plumber, HVAC technician, or qualified mechanical contractor in accordance with applicable codes including the IPC and IFGC. Shut off system pressure and bleed the line before removing or installing the gauge. Apply appropriate thread sealant to the NPT connection and tighten to snug fit without over-torquing the brass fittings. Verify the installed gauge range is appropriate for the system operating pressure before returning the system to service.
