Ashcroft 94343 Pressure Gauge 0-600 Psi 3.5 in Dial Npt

Product Description

The ASHCROFT 94343 is an analog industrial pressure gauge designed for accurate pressure monitoring in demanding trade and process applications. It features a 3.5-inch dial with a 0 to 600 psi range and delivers 1% of scale accuracy. The gauge uses a 316 stainless steel Bourdon tube and a 304/316 stainless steel case, making it suitable for environments where corrosion resistance is required. It mounts via a lower 1/4-inch NPT connection and is not liquid-filled. The polycarbonate lens protects the dial face. Licensed HVAC techs, plumbers, and industrial service technicians install this gauge in piping and pressure systems.

The ASHCROFT 94343 is suited for residential and commercial plumbing, HVAC, and light industrial piping applications where a durable, corrosion-resistant pressure gauge is needed at a lower-mount configuration. The lower NPT connection allows direct installation into pipe nipples, manifolds, tee fittings, or pressure ports. Its stainless steel construction makes it appropriate for mildly aggressive media and outdoor or wet-location installations where the IP54 and IP65/NEMA 4 ratings provide meaningful protection against dust and water ingress.

Key Features

• 0 to 600 psi range with 1% of scale accuracy for reliable pressure readings
• 3.5-inch analog dial for easy at-a-glance readout
• 316 stainless steel Bourdon tube for corrosion resistance in aggressive media
• 304/316 stainless steel case rated for wet and outdoor locations
• Polycarbonate lens protects the dial face from impact and moisture
• Meets CRN, IP54, IP65/NEMA 4, PED, and RoHS standards

Compatibility

Designed as an OEM-style lower-mount replacement or new-installation pressure gauge for industrial, HVAC, and plumbing systems using standard 1/4-inch NPT lower-mount connections.

Installation Notes

Installation is typically performed by a licensed plumber, HVAC technician, or industrial pipefitter. Always isolate and depressurize the system completely before removing or installing any pressure gauge. Use appropriate thread sealant on the NPT threads and tighten to fitting manufacturer recommendations without overtightening the gauge case. Verify the system pressure range does not exceed the 600 psi maximum rated range of the gauge.
