Ashcroft 251009S02LLL160 Pressure Gauge 0-160 Psi

Product Description

The ASHCROFT 251009S02LLL160 is an industrial pressure gauge designed for accurate pressure monitoring in demanding fluid and gas systems. It features a 2.5-inch analog dial with a 0 to 160 psi range and a 1 percent of scale accuracy rating. The case is constructed from 304/316 stainless steel, and all wetted parts are stainless steel, making it suitable for corrosive media and harsh environments. The lower-mount, 1/4-inch MNPT connection allows direct in-line installation. This gauge is a dry (no-fill) unit with a polycarbonate lens. It is installed by licensed plumbers, HVAC technicians, pipefitters, and industrial maintenance professionals.

This gauge is used in residential and commercial applications where reliable pressure indication is required, including HVAC systems, plumbing lines, compressed air systems, and process piping. The stainless steel wetted parts make it a strong choice for mildly corrosive fluids or steam-adjacent environments. The lower-mount configuration suits panel or pipe installations where a direct bottom connection is practical. The 2.5-inch dial provides a clearly readable scale for field technicians.

Compatibility

Designed as an OEM-style industrial pressure gauge for use in plumbing, HVAC, compressed air, and process piping systems requiring a 1/4-inch MNPT lower-mount connection and a 0 to 160 psi measurement range.

Installation Notes

Installation should be performed by a qualified plumber, pipefitter, or HVAC technician in accordance with applicable local codes including IPC and IFGC where relevant. Isolate and depressurize the system completely before installing or removing the gauge. Apply thread sealant or PTFE tape to the MNPT threads as appropriate for the media and system pressure. Do not over-tighten the threaded connection, as this can damage the gauge socket or fitting.
