Ashcroft 95291 Pressure Gauge 1500 Psi 2.5 in Dial Npt

Product Description

The ASHCROFT 95291 is a liquid-filled analog pressure gauge designed for accurate system pressure monitoring in demanding trade applications. It features a 2.5-inch dial graduated from 0 to 1,500 psi and achieves 1% of scale accuracy across its full range. The stainless steel case provides corrosion resistance suitable for wet, oily, or chemically active environments. Liquid filling dampens pointer vibration and protects internal components from pulsation damage, extending service life in high-cycle systems. Licensed plumbers, HVAC technicians, and mechanical contractors install this gauge on systems where reliable pressure indication is critical to safe operation.

This gauge is well suited for residential and light commercial plumbing, HVAC refrigerant circuits, compressed air systems, hydraulic lines, and industrial process piping where a 1/4-inch NPT center back mount connection is standard. The center back mount orientation allows the gauge to sit flush against panels or pipe assemblies, keeping the dial clearly visible without extending the gauge body forward into the work area. Its compact 2.5-inch dial size fits tight instrument clusters and standard gauge ports.

Key Features

• 0 to 1,500 psi pressure range with 1% of scale accuracy
• Liquid-filled case dampens vibration and pulsation for stable pointer reading
• Stainless steel case resists corrosion in wet and chemically active environments
• 2.5-inch analog dial for clear, direct pressure reading
• 1/4-inch NPT center back mount for flush panel or pipe installation

Compatibility

Designed as an OEM-style replacement or service gauge for systems equipped with a 1/4-inch NPT center back mount gauge port operating within a 0 to 1,500 psi range.

Installation Notes

Installation is typically performed by a licensed plumber, HVAC technician, or mechanical contractor in accordance with applicable IPC or IFGC requirements. Isolate and depressurize the system fully before removing or installing any pressure gauge. Apply thread sealant appropriate for the service fluid to the NPT threads and tighten to the fitting snug-plus-turns by hand first to avoid cross-threading. Do not over-tighten the gauge body, as stainless steel fittings can gall; use a wrench on the hex of the gauge connection, not on the case.
