Pressure gauge Afriso RF 100 RAD Ø100 mm 0–1.6 bar 1/2" connection class 2.5 (MPN 63610)

The Afriso RF 100 RAD pressure gauge is a mechanical instrument with a 100 mm dial and a measuring range of 0–1.6 bar. Designed for use in heating systems, the gauge provides an analog indication of system pressure via a clear, easy-to-read dial. The device has a 1/2" threaded connection and an accuracy class of 2.5, making it suitable for routine monitoring of boiler and radiator pressure in residential and light-commercial installations.

Advantages

This pressure gauge offers straightforward mechanical sensing without the need for power, ensuring continuous operation and simple maintenance. The 100 mm diameter dial provides good readability from a distance, and the 1/2" threaded connection is compatible with common heating fittings. Class 2.5 accuracy delivers adequate precision for everyday system checks and preventive maintenance tasks.

Suitable for

• Monitoring boiler pressure in residential heating systems
• Checking radiator and distribution circuit pressure
• Routine maintenance and pressure verification in light-commercial installations
• Replacement of standard mechanical gauges with compatible mounting

Key specifications

• Dial diameter: 100 mm
• Measuring range: 0 to 1.6 bar
• Connection: 1/2" threaded
• Display type: analog (dial and pointer)
• Accuracy class: 2.5
• Operating principle: mechanical pressure sensing

How to use

Install the gauge by screwing the 1/2" threaded connection into a compatible port on the boiler, manifold, or pressure tapping point using appropriate sealing material to prevent leaks. Mount the gauge where the dial is visible and protected from direct heat sources and mechanical damage. After installation, bring the system up to normal operating pressure and check the pointer against the dial. Use the gauge for regular visual inspections and record readings as part of routine maintenance. If the pointer sticks or shows erratic movement, depressurize the system before removing the gauge for inspection or replacement.

Usage recommendations

For reliable readings, avoid installing the gauge in locations exposed to strong vibrations or temperatures beyond the manufacturer's specified operating range. Periodically compare readings with a calibrated reference gauge during preventive maintenance; replace the instrument if accuracy degrades or the dial becomes illegible.
