Ashcroft 83252 Pressure Gauge 1500 Psi 3.5 in Dial Npt

Product Description

The ASHCROFT 83252 is an analog pressure gauge built for accurate system pressure monitoring in demanding trade applications. It features a 3.5-inch dial and a pressure range of 0 to 1,500 psi, with a stated accuracy of 1 percent of scale. The stainless steel case provides corrosion resistance in wet or chemically aggressive environments. Connection is via a 1/4-inch NPT center back mount, allowing direct inline or manifold installation. HVAC technicians, plumbers, and mechanical contractors use this gauge on refrigeration systems, hydronic heating loops, compressed air lines, and process piping where reliable pressure indication is required.

This gauge suits residential and light commercial mechanical systems where a compact, dry-fill analog instrument is appropriate. The center back mount configuration allows the gauge to sit flush against a panel or pipe assembly without an extended stem. The 3.5-inch dial provides clear readability from a typical service distance. It is suited for installations where 1,500 psi maximum system pressure falls within the expected operating range, including high-pressure water, compressed air, and refrigerant-adjacent applications.

Key Features

• 0 to 1,500 psi pressure range suits high-pressure service applications
• 1 percent of scale accuracy for reliable field readings
• 3.5-inch analog dial for clear, at-a-glance readability
• Stainless steel case resists corrosion in wet and industrial environments
• 1/4-inch NPT center back mount for straightforward panel or pipe installation
• Dry-fill construction — no liquid fill to manage or contain

Compatibility

Designed as an OEM-style replacement or direct-install pressure gauge for mechanical systems requiring a 1/4-inch NPT center back mount instrument rated to 1,500 psi.

Installation Notes

Installation should be performed by a licensed plumber, HVAC technician, or qualified mechanical contractor. Depressurize and isolate the system completely before removing an existing gauge or making new connections. Apply appropriate thread sealant to the NPT threads per IPC and IFGC guidelines — do not overtighten, as stainless steel fittings can gall. Verify the system operating pressure does not exceed the 1,500 psi rated maximum of this gauge.
