Ashcroft 662876000517 Pressure Gauge 0-15 Psi 2in Npt

Product Description

The ASHCROFT 662876000517 is a commercial-grade analog pressure gauge designed for monitoring system pressure in a wide range of industrial and mechanical applications. It features a 2 inch dial with a 0 to 15 psi range and delivers 3-2-3 percent of scale accuracy across the full span. The steel case and polycarbonate lens provide durable protection in typical service environments. Connection is made via a 1/4 inch NPT center back mount fitting, making it straightforward to install inline or on manifold ports. Licensed HVAC technicians, plumbers, and pipefitters routinely use this gauge for low-pressure system diagnostics and monitoring.

This gauge is suited for residential and light commercial applications where low-pressure monitoring is required. Common install scenarios include boiler systems, water supply lines, air compressor outlets, and HVAC refrigerant or water circuit test ports. The center back mount configuration is standard on panel-mounted and pipe-mounted gauge assemblies. The 2 inch dial size is compact enough for tight installations while remaining readable in field conditions. The analog Bourdon tube design requires no power source and provides continuous pressure indication.

Key Features

• 0 to 15 psi pressure range for low-pressure system monitoring
• 3-2-3 percent of scale accuracy across the full dial span
• 2 inch analog dial with polycarbonate lens for clear readability
• Bronze Bourdon tube construction for reliable pressure response
• Steel case provides durable housing for field and panel use
• 1/4 inch NPT center back mount for straightforward pipe or manifold installation
• CRN certified for applicable pressure vessel and piping code compliance

Compatibility

Designed as an OEM-style replacement or new-install gauge for low-pressure commercial and residential piping systems requiring a 1/4 inch NPT center back mount connection and a 0 to 15 psi range.

Installation Notes

Installation should be performed by a licensed plumber, pipefitter, or qualified HVAC technician in accordance with applicable local codes and ASME B40.100 gauge installation guidelines. Isolate and depressurize the system completely before removing an existing gauge or threading in the new unit. Apply thread sealant or PTFE tape to the NPT threads per standard trade practice, and avoid over-tightening, which can damage the gauge socket. Do not use the gauge dial or case as a wrench grip — use an appropriately sized open-end wrench on the hex of the gauge socket only.
