Ashcroft 662876000135 Pressure Gauge 0-30 Psi 1-1/2 in

Product Description

The ASHCROFT 662876000135 is a commercial-grade analog pressure gauge designed for monitoring system pressure in HVAC, plumbing, and light industrial applications. The gauge features a 1-1/2 inch dial with a 0 to 30 psi range and a 3-2-3 percent of scale accuracy rating, making it suitable for low-pressure monitoring tasks where a compact footprint is required. The steel case houses a bronze Bourdon tube mechanism, and the polycarbonate lens protects the dial face from moisture and impact. A 1/8 inch NPT center back mount connection allows direct installation into threaded ports on piping, manifolds, or equipment panels. Licensed HVAC technicians and plumbers are the typical installers for this gauge type.

This gauge is intended for commercial pressure monitoring in residential and light commercial systems where low-pressure ranges are involved. Common applications include monitoring water pressure, compressed air lines, and low-pressure gas or fluid circuits. The center back mount configuration suits panel-mount or direct pipe installations where the connection enters from the rear of the gauge body. The 1-1/2 inch dial diameter is appropriate for close-quarters installations where panel space is limited.

Key Features

• 0 to 30 psi pressure range for low-pressure system monitoring
• 3-2-3 percent of scale accuracy across the full dial range
• 1-1/2 inch analog dial with polycarbonate lens for impact and moisture resistance
• Bronze Bourdon tube construction for reliable pressure sensing
• Steel case with 1/8 inch NPT center back mount connection
• CRN certified for use in applicable jurisdictions

Compatibility

Designed as an OEM-style replacement or add-on commercial pressure gauge for systems with 1/8 inch NPT threaded ports operating in the 0 to 30 psi range.

Installation Notes

Installation is typically performed by a licensed plumber or HVAC technician. Depressurize and isolate the system completely before removing or installing any pressure gauge. Apply thread sealant tape or compound to the NPT threads per the fitting manufacturer and applicable IPC or IFGC guidelines. Do not over-tighten the gauge body, as this can damage the Bourdon tube or crack the case.
