Wika 9318240 Pressure Gauge 1000 Psi 2.5 in Dial Back Mount

Product Description

The WIKA 9318240 is a liquid-filled analog pressure gauge designed for industrial and mechanical system monitoring. It features a 2.5-inch brass case dial and a back-mount configuration with a 1/4-inch threaded connection. The gauge reads from 0 to 1,000 psi and holds a 1.5% of scale accuracy rating. Liquid filling dampens needle vibration and protects internal components in high-pulse or high-vibration applications. HVAC technicians, plumbers, and pipefitters install this type of gauge on pressure lines, manifolds, and equipment skids where a reliable, readable pressure indication is required.

This gauge suits residential and light commercial applications where back-mount installation is needed and panel or wall-mounted gauge configurations are common. The 1/4-inch threaded connection is a standard size across a wide range of pressure-rated fittings and adapters used in HVAC, plumbing, and general fluid system service. The brass case provides corrosion resistance in typical indoor mechanical environments. It is well suited for monitoring water, air, and compatible fluid pressures in piped systems.

Key Features

• Liquid-filled case reduces needle flutter in high-vibration and high-pulse systems
• 1.5% of scale accuracy for reliable pressure monitoring
• 2.5-inch dial diameter for clear, direct reading
• Back-mount orientation supports panel and wall-mounted installations
• 1/4-inch threaded connection fits standard fittings and adapters
• Brass case construction for corrosion resistance in typical service environments

Compatibility

Designed as an OEM-style replacement or direct-install analog pressure gauge for residential and light commercial piping systems requiring a back-mount, 1/4-inch threaded, 0 to 1,000 psi gauge.

Installation Notes

Installation is typically performed by a licensed plumber, pipefitter, or HVAC technician. Depressurize and isolate the system fully before removing an existing gauge or threading in a new one. Apply thread sealant appropriate for the system fluid and pressure rating to the male threads before installation. Do not overtighten the threaded connection, as brass fittings can be damaged by excessive torque.
