Ashcroft 94242 Pressure Gauge 0-3000 Psi 3.5in Dial Npt

Product Description

The ASHCROFT 94242 is an analog industrial pressure gauge built for demanding service environments. It features a 3.5-inch dial, a 0 to 3000 psi measurement range, and a 1/4-inch NPT lower-mount connection. The Bourdon tube is 316 stainless steel, and the case is 304/316 stainless steel, making this gauge well-suited for corrosive or wet locations. Accuracy is rated at 1 percent of scale. A polycarbonate lens protects the dial face from impact and moisture. This gauge is used by HVAC technicians, plumbers, pipefitters, and industrial maintenance personnel who need reliable pressure indication on fluid or gas systems.

The 94242 is intended for industrial pressure monitoring applications including hydraulic systems, compressed air lines, water supply systems, and process piping. The lower-mount NPT connection allows direct installation into threaded ports on manifolds, pipe tees, and equipment panels. Its stainless steel construction makes it appropriate for outdoor installations or environments where moisture, mild chemicals, or washdown conditions are present. This is a dry-fill gauge, meaning it does not contain glycerin or other liquid fill.

Key Features

• 3.5-inch analog dial for easy readability at a distance
• 316 stainless steel Bourdon tube resists corrosion in harsh media
• 304/316 stainless steel case rated for wet and corrosive environments
• Polycarbonate lens provides impact and moisture resistance
• 1/4-inch NPT lower-mount connection for direct pipe or manifold installation
• Dry-fill construction — no liquid fill

Compatibility

Designed as an OEM-style replacement or new-installation industrial pressure gauge for systems requiring a 1/4-inch NPT lower-mount gauge rated to 3000 psi.

Installation Notes

Installation is typically performed by licensed plumbers, pipefitters, or qualified industrial maintenance technicians. Isolate and depressurize the system completely before removing or installing any pressure gauge. Apply thread sealant or PTFE tape to the NPT threads per local plumbing or mechanical code requirements, and avoid over-tightening, which can crack the gauge socket. Verify that the system media and operating pressure are compatible with stainless steel wetted parts before placing the gauge in service.
