Ashcroft 94343XLL Pressure Gauge 0-600 Psi 3.5 in Lower Mount

Product Description

The ASHCROFT 94343XLL is an industrial-grade analog pressure gauge built for demanding service environments. It features a 3.5-inch dial with a 0 to 600 psi range, a stainless steel case, and stainless steel wetted parts, making it suitable for applications where corrosion resistance is critical. The Bourdon tube is constructed from 316 stainless steel for durability against aggressive media. Accuracy is rated at 1 percent of scale, which meets standard requirements for most industrial and mechanical system monitoring. The gauge ships dry with no liquid fill and mounts via a 1/4-inch MNPT lower connection. Technicians in HVAC, plumbing, and industrial process work rely on this type of gauge for reliable pressure indication at system test points and service panels.

The 94343XLL is suited for use in commercial and industrial installations where a lower-mount configuration is required for panel or manifold mounting. The 3.5-inch dial provides clear readability in tight mechanical rooms or equipment enclosures. Its no-fill design keeps installation simple and eliminates concerns about glycerin or silicone fluid compatibility with the measured media. Typical applications include boiler systems, compressed air lines, water supply systems, and process piping where sustained pressure monitoring is needed.

• Polycarbonate lens provides impact resistance and clear dial visibility
• Certified to CRN, IP54, IP65/NEMA 4, PED, and RoHS standards

Compatibility

Designed as an OEM-style replacement or direct-install industrial pressure gauge for lower-mount MNPT applications requiring a 3.5-inch dial and 0 to 600 psi range in commercial and industrial piping and mechanical systems.

Installation Notes

Installation should be performed by a qualified plumber, pipefitter, or mechanical technician in accordance with applicable local codes and system requirements. Shut off and depressurize the system completely before removing or installing any pressure gauge. Apply appropriate thread sealant to the 1/4-inch MNPT threads and tighten to snug fit without over-torquing the stainless steel fitting. Verify the gauge range is appropriate for the system operating pressure before placing the system back in service.
