Ashcroft 94486 Pressure Gauge 0-100 Psi 3.5in Dial Npt

Product Description

The ASHCROFT 94486 is a liquid-filled industrial pressure gauge designed for accurate pressure monitoring in demanding service environments. It features a 3.5-inch analog dial with a 0 to 100 psi range and delivers 1 percent of full-scale accuracy. The gauge uses a 316 stainless steel Bourdon tube and a 304/316 stainless steel case, making it suitable for corrosive media and wash-down applications. A polycarbonate lens protects the dial face. The liquid-fill dampens pointer vibration and reduces internal wear. Licensed HVAC technicians, plumbers, and industrial service pros install this type of gauge as part of pressure monitoring systems, test rigs, and process piping.

The ASHCROFT 94486 is suited for residential and commercial applications where a durable, corrosion-resistant pressure gauge is required. The lower-mount, 1/4-inch NPT connection allows direct in-line installation on piping, manifolds, pump outlets, and pressure test ports. Liquid-fill construction makes it appropriate for high-vibration environments such as compressor skids, booster pump systems, and hydraulic circuits. It carries CRN, IP54, IP65/NEMA 4, PED, and RoHS certifications, supporting use in both standard and regulated installations.

Key Features

• 316 stainless steel Bourdon tube for compatibility with corrosive media
• 304/316 stainless steel case suitable for wash-down and outdoor environments
• 3.5-inch analog dial for clear, at-a-distance readability
• Certified to CRN, IP54, IP65/NEMA 4, PED, and RoHS standards

Compatibility

Designed as a direct-connect industrial pressure gauge for systems using standard 1/4-inch NPT lower-mount connections on piping, manifolds, and equipment pressure ports.

Installation Notes

Installation is typically performed by a licensed plumber, HVAC technician, or industrial mechanic. Isolate and depressurize the system fully before removing or installing any pressure gauge. Apply thread sealant appropriate for the service media to the NPT threads; avoid over-tightening, which can damage the gauge socket. Verify that the gauge pressure range is appropriate for the system's maximum operating pressure before returning the system to service.
