Ashcroft 94339 Pressure Gauge 0-160 Psi 3-1/2 in Lower Mount

Product Description

The ASHCROFT 94339 is an analog industrial pressure gauge designed for accurate pressure monitoring in mechanical, plumbing, HVAC, and process systems. It features a 3-1/2 inch dial with a 0 to 160 psi range and delivers 1% of scale accuracy, making it suitable for applications where reliable readings are essential. The gauge uses a 316 stainless steel Bourdon tube and a 304/316 stainless steel case, providing corrosion resistance in demanding environments. It is not liquid filled and mounts via a 1/4 inch NPT lower-mount connection. Licensed HVAC technicians, plumbers, and industrial service professionals are the typical installers.

This gauge is suited for residential and commercial installations where a durable, dry-type pressure gauge is required on water, gas, or air lines. The lower-mount NPT configuration makes it a standard fit for pipe-mounted applications on pressure lines, test ports, and system manifolds. The polycarbonate lens protects the dial face from dust and moisture, and the unit carries IP54 and IP65/NEMA 4 ratings for use in wet or washdown-prone environments. It is compliant with CRN, PED, and RoHS standards, supporting use in regulated installations.

Key Features

• 0 to 160 psi range with 1% of scale accuracy for reliable pressure readings
• 316 stainless steel Bourdon tube resists corrosion in harsh media
• 304/316 stainless steel case for long service life in industrial environments
• 1/4 inch NPT lower-mount connection for standard pipe-mount installations
• Polycarbonate lens with IP54 and IP65/NEMA 4 ingress protection
• CRN, PED, and RoHS compliant for use in regulated and export applications

Compatibility

Designed as an OEM-style replacement or direct-install industrial pressure gauge for pipe-mounted pressure monitoring points using 1/4 inch NPT lower-mount connections on water, air, or gas lines.

Installation Notes

Installation is performed by licensed plumbers, HVAC technicians, or qualified industrial mechanics. Shut off and depressurize the system completely before installing or replacing any pressure gauge. Apply thread sealant or PTFE tape to the NPT threads per applicable IPC or IFGC guidelines. Do not overtighten the gauge body; use a wrench on the hex fitting only to avoid case damage or dial misalignment.
