Ashcroft 82108 Pressure Gauge 300 Psi 2.5 in Npt

Product Description

The ASHCROFT 82108 is an analog pressure gauge built for trade professionals who need accurate, reliable pressure readings in demanding service environments. It features a 2.5 inch dial, a 0 to 300 psi range, and a stainless steel case for corrosion resistance. The center back mount configuration positions the 1/4 inch NPT connection directly at the rear of the gauge, which simplifies panel or manifold installations. Accuracy is rated at 1 percent of scale across the full range. The gauge is dry (non-liquid-filled), making it straightforward to install and service without fluid containment concerns. HVAC technicians, plumbers, and industrial service techs all work with gauges in this class.

This gauge is suited for residential and light commercial applications where monitoring system pressure is part of routine service or commissioning. Typical uses include HVAC refrigerant or water pressure monitoring, plumbing system pressure verification, compressor output monitoring, and general process pressure measurement. The 1/4 inch NPT center back mount makes it a common fit for pressure taps on boilers, air compressors, pump systems, and similar equipment where a panel-flush or back-connected gauge is preferred.

Key Features

• 0 to 300 psi analog pressure range
• 2.5 inch dial for clear, at-a-glance readings
• 1 percent of scale accuracy across the full range
• 1/4 inch NPT center back mount connection
• Stainless steel case for corrosion resistance in wet or harsh environments
• Dry (non-liquid-filled) construction for simple installation and maintenance

Compatibility

Designed as an OEM-style replacement or direct-install pressure gauge for systems using a 1/4 inch NPT center back mount connection and requiring a 0 to 300 psi measurement range.

Installation Notes

Installation is typically performed by licensed plumbers, HVAC technicians, or pipefitters. Always depressurize and isolate the system before removing or installing any pressure gauge. Apply thread sealant or PTFE tape to the NPT threads in accordance with applicable plumbing and mechanical codes, and do not overtighten, as stainless steel fittings can gall. Verify that the system operating pressure does not exceed the 300 psi maximum range of the gauge.
