Ashcroft 92646 Pressure Gauge 0-200 Psi 6 Inch Npt Lower Mount

Product Description

The ASHCROFT 92646 is an analog pressure gauge designed for accurate pressure monitoring in mechanical, HVAC, plumbing, and industrial service applications. It features a 6-inch aluminum-case dial with a glass lens, a 1/4-inch NPT lower-mount connection, and a Bourdon tube constructed from bronze. The gauge reads from 0 to 200 psi with an accuracy of 0.25 percent of scale, making it a reliable instrument for systems where tight pressure verification is required. Licensed technicians and service professionals use this gauge during system commissioning, troubleshooting, and routine inspections.

This gauge is suited for residential and light commercial HVAC systems, hydronic heating, compressed air, and general plumbing pressure monitoring. The lower-mount NPT connection allows direct installation into a pipe tee, manifold port, or test port without a separate adapter in most standard configurations. The 6-inch dial provides clear readability from a distance in mechanical rooms and utility spaces. It meets CRN standards, making it appropriate for use in jurisdictions that require Canadian Registration Number compliance.

Compatibility

Designed as an OEM-style replacement or new-installation pressure gauge for residential and commercial HVAC, hydronic, compressed air, and plumbing systems using standard 1/4-inch NPT lower-mount ports.

Installation Notes

Installation is typically performed by a licensed HVAC technician, plumber, or pipefitter. Depressurize and isolate the system completely before removing any existing gauge or fitting the new gauge into the port. Apply thread sealant rated for the system fluid and pressure range to the NPT threads before installation. Follow applicable local codes, including IPC and IFGC requirements, for pressure gauge placement and system test procedures.
