Ashcroft 94906 Pressure Gauge 0-160 Psi 2.5 in Dial Npt

Product Description

The ASHCROFT 94906 is a liquid-filled industrial pressure gauge designed for accurate pressure monitoring in demanding mechanical and process applications. It features a 2.5-inch analog dial with a 0 to 160 psi range and delivers 1% of scale accuracy across that range. The stainless steel case and 316 stainless steel Bourdon tube provide corrosion resistance in wet or chemically aggressive environments. The liquid fill dampens pointer vibration and pulsation, extending service life and improving readability. Licensed plumbers, HVAC technicians, and industrial mechanics install this gauge on piping systems requiring continuous pressure indication.

This gauge is suited for residential and commercial plumbing, HVAC hydronic systems, compressed air lines, and light industrial process piping where a compact, corrosion-resistant gauge with rear entry is required. The lower back mount configuration allows installation directly into a pipe fitting or manifold with a 1/4-inch NPT male connection, keeping the dial face perpendicular to the pipe run for easy reading. Its IP54 and IP65/NEMA 4 ratings make it appropriate for indoor and outdoor installations exposed to moisture or washdown conditions.

Key Features

• Liquid-filled design dampens vibration and pulsation for stable readings
• 1% of scale accuracy across the full 0 to 160 psi range
• 316 stainless steel Bourdon tube for corrosion resistance in aggressive media
• 304/316 stainless steel case rated IP54 and IP65/NEMA 4 for wet environments
• Polycarbonate lens for impact and chemical resistance
• Lower back mount with 1/4-inch NPT connection for direct pipe installation
• Compliant with CRN, PED, and RoHS standards

Compatibility

Designed as an OEM-style replacement or new-installation gauge for industrial, commercial, and residential piping systems requiring a 2.5-inch dial, 1/4-inch NPT lower back mount pressure gauge rated to 160 psi.

Installation Notes

Installation is performed by licensed plumbers, HVAC technicians, or qualified industrial mechanics. Depressurize and isolate the system completely before removing an existing gauge or installing this unit. Apply thread sealant tape or compound rated for the service media to the NPT threads; do not overtighten, as stainless steel threads can gall. Follow applicable codes including IPC and IFGC for plumbing and gas applications respectively.
