Ashcroft 94473 Pressure Gauge 0-15 Psi 2.5in Dial Npt

Product Description

The ASHCROFT 94473 is a liquid-filled industrial pressure gauge designed for accurate, reliable pressure monitoring in demanding service environments. It features a 2.5-inch analog dial with a 0 to 15 psi range and delivers 1 percent of scale accuracy. The stainless steel case and 316 stainless steel Bourdon tube make it suitable for corrosive media and harsh ambient conditions. The liquid-filled design dampens needle vibration and reduces wear on internal components, extending service life in high-cycle or pulsating systems. Licensed HVAC technicians, plumbers, and industrial service professionals install this gauge on process lines, low-pressure systems, and test manifolds where a compact, durable instrument is required.

This gauge is well suited for residential and light commercial plumbing, HVAC hydronic systems, compressed air lines, and industrial process piping operating at or below 15 psi. The lower-mount NPT connection allows direct in-line installation on pipes, manifolds, or equipment panels. The 2.5-inch dial face provides a clear analog readout in space-constrained installations. Its IP54 and IP65/NEMA 4 ratings make it appropriate for wet or washdown locations.

Key Features

• 0 to 15 psi range with 1 percent of scale accuracy for precise low-pressure measurement
• Liquid-filled construction dampens vibration and protects internal mechanism from pulsation
• 316 stainless steel Bourdon tube for compatibility with mildly corrosive media
• 304/316 stainless steel case for corrosion resistance in harsh environments
• Polycarbonate lens resists impact and maintains dial legibility
• IP54 and IP65/NEMA 4 rated for use in wet or washdown service areas
• Meets CRN, PED, and RoHS standards

Compatibility

Designed as an OEM-style replacement or new-installation industrial pressure gauge for systems requiring a 1/4 inch NPT lower-mount connection and a 0 to 15 psi measurement range. Part of the ASHCROFT 1009 Series.

Installation Notes

Installation is typically performed by a licensed plumber, HVAC technician, or instrumentation technician. Isolate and depressurize the system completely before removing or installing the gauge. Apply thread sealant or PTFE tape to the NPT threads per standard practice and applicable plumbing codes. Do not over-tighten the threaded connection, and avoid using the gauge body as a lever during installation.
