Ashcroft 662876124374 Pressure Gauge 0-300 Psi 2 in

Product Description

The ASHCROFT 662876124374 is a commercial-grade analog pressure gauge designed for monitoring system pressure in a wide range of industrial and mechanical applications. It features a 2-inch dial with a 0 to 300 psi range and delivers 3-2-3 percent of scale accuracy, meaning the reading stays within 3 percent at the low and high ends of the scale and within 2 percent in the mid-range. The steel case protects internal components in demanding environments, while the polycarbonate lens provides clear dial visibility. The Bourdon tube is constructed from bronze, a standard material for general-purpose pressure service. Installation is via a 1/4-inch NPT center back mount connection, making it compatible with common pipe fittings found in most mechanical systems.

This gauge is suited for use in commercial HVAC systems, plumbing installations, compressed air lines, hydronic heating systems, and general industrial piping where reliable pressure monitoring is required. The center back mount configuration is commonly used in panel-mount or pipe-mount setups where the gauge face needs to be flush and visible. Licensed plumbers, HVAC technicians, and mechanical contractors typically specify this gauge for service and monitoring points throughout pressurized systems.

Key Features

• 2-inch analog dial with 0 to 300 psi pressure range
• 3-2-3 percent of scale accuracy for reliable mid-range and full-scale readings
• Bronze Bourdon tube construction for general-purpose pressure service
• Steel case for durability in commercial and industrial environments
• Polycarbonate lens for clear, impact-resistant dial visibility
• 1/4-inch NPT center back mount connection for straightforward installation
• CRN certified for use in applicable Canadian pressure vessel applications

Compatibility

Designed as an OEM-style replacement or service gauge for commercial and industrial pressurized systems requiring a 2-inch dial, 1/4-inch NPT center back mount connection, and a 0 to 300 psi measurement range.

Installation Notes

Installation should be performed by a licensed plumber, HVAC technician, or qualified mechanical contractor. De-pressurize and isolate the system completely before removing or installing any pressure gauge. Use appropriate thread sealant on NPT connections and avoid overtightening, which can crack the case or distort the Bourdon tube. Verify that the system pressure range does not exceed the gauge maximum rating of 300 psi during normal or surge conditions.
