Ashcroft 351009S2LXLL800 Pressure Gauge 0-800 Psi

Product Description

The ASHCROFT 351009S2LXLL800 is an analog industrial pressure gauge built for demanding service environments. It features a 3.5-inch dial with a 0 to 800 psi range, a 304/316 stainless steel case, and fully stainless steel wetted parts. The Bourdon tube is 316 stainless steel, making it suitable for use with corrosive media and washdown-exposed installations. Accuracy is rated at 1 percent of scale. The gauge is dry (no liquid fill) and mounts from the lower position via a 0.25-inch MNPT male connection. HVAC technicians, plumbers, and industrial maintenance crews install this type of gauge to monitor system pressure in piping, process lines, and mechanical equipment.

This gauge is designed for industrial pressure monitoring applications where corrosion resistance and reliable analog readout are priorities. Lower-mount configuration suits panel installations and direct pipe-thread connections on manifolds, test ports, and process equipment. The polycarbonate lens protects the dial face in wet or dusty environments. It is appropriate for residential and commercial mechanical systems as well as light industrial process lines handling fluids compatible with stainless steel wetted surfaces.

Compatibility

Designed as an OEM-style replacement or new-installation industrial pressure gauge for systems with 0.25-inch MNPT lower-mount connection points operating within a 0 to 800 psi range and compatible with stainless steel wetted parts.

Installation Notes

Install and service by a qualified technician familiar with pressurized piping systems. Depressurize and isolate the system completely before removing or installing any pressure gauge. Apply appropriate thread sealant to the MNPT connection per the applicable piping code; do not overtighten, as stainless fittings can gall. Verify the operating pressure range of the system does not exceed the gauge maximum before placing in service.
