Ashcroft 662876128150 Pressure Gauge 200 Psi 1.5 in Npt

Product Description

The ASHCROFT 662876128150 is an analog pressure gauge designed for monitoring system pressure in HVAC, plumbing, and related mechanical applications. It features a 1.5-inch steel-cased dial with a range of 0 to 200 psi and connects via a 1/8-inch NPT center back mount fitting. The compact dial size and back-mount configuration make it suited for panel-mount and tight-space installations where a front-entry connection is not practical. Licensed plumbers, HVAC technicians, and pipefitters install this type of gauge as part of pressure monitoring assemblies on boilers, compressors, water lines, and similar systems.

This gauge is appropriate for residential and light commercial applications where a small-format, low-cost analog pressure indicator is required. Its center back mount orientation allows it to sit flush against a panel or manifold surface, keeping the face readable while minimizing the footprint. The 1/8-inch NPT thread is a common size found on boiler tappings, air compressor manifolds, pump outlets, and small-diameter piping systems. It is sold individually and is a direct replacement for worn or damaged small-dial pressure gauges of the same configuration.

Key Features

• 0 to 200 psi analog pressure range for system monitoring
• 1.5-inch dial diameter for compact, panel-friendly installation
• 1/8-inch NPT center back mount for flush or manifold mounting
• Steel case construction for durability in trade environments
• Analog dial type with no batteries or electronics required

Compatibility

Designed as an OEM-style replacement for small-dial analog pressure gauges with 1/8-inch NPT center back mount connections in residential and light commercial mechanical systems.

Installation Notes

Installation is typically performed by a licensed plumber or HVAC technician. Shut off system pressure and bleed the line before removing or installing any pressure gauge. Apply thread sealant tape to the NPT threads and tighten with an appropriately sized wrench. Do not over-tighten the fitting, as this can crack the gauge body or distort the threaded port.
