Ashcroft 94336XLL Pressure Gauge 0-30 Psi 3.5in Lower Mount

Product Description

The ASHCROFT 94336XLL is an industrial analog pressure gauge designed for accurate system pressure monitoring across a wide range of commercial and industrial applications. It features a 3.5-inch dial with a 0 to 30 psi range and delivers 1% of scale accuracy via a 316 stainless steel Bourdon tube mechanism. The stainless steel case carries a 304/316 grade designation, and all wetted parts are stainless steel, making this gauge well-suited for environments where corrosion resistance and fluid compatibility matter. A polycarbonate lens protects the dial face. Licensed HVAC techs, plumbers, and industrial service technicians are the primary installers for gauges of this type.

This gauge fits lower-mount installations with a 1/4-inch MNPT threaded connection. It is a no-fill, non-liquid-filled unit, making it straightforward to install on water, air, gas, and compatible fluid systems where a dry gauge is acceptable. The 3.5-inch dial diameter provides clear readability in panel, manifold, and inline applications. It meets CRN, IP54, IP65/NEMA 4, PED, and RoHS standards, broadening its suitability for installations subject to environmental exposure or regulatory compliance requirements.

Compatibility

Designed as an OEM-style replacement or new-installation dry pressure gauge for industrial, commercial, and mechanical systems requiring a lower-mount 1/4-inch MNPT connection with a 0 to 30 psi range.

Installation Notes

Installation is typically performed by licensed plumbers, HVAC technicians, or industrial mechanics. Always depressurize and isolate the system before removing or installing the gauge. Apply thread sealant tape or compound to the MNPT threads in accordance with local plumbing and mechanical codes. Do not overtighten the brass or stainless fittings at the port, as this may damage the gauge socket or connected piping.
