Pressure gauge Afriso RF 80 rad, Ø80 mm, 0–2.5 bar, G1/2" connection, accuracy class 2.5 (63561)

The Afriso RF 80 rad pressure gauge is a mechanical instrument designed to monitor fluid pressure in heating and hydronic systems. It features an 80 mm diameter dial with a measuring range of 0–2.5 bar and a radial G1/2" connection. The gauge provides straightforward, analog readings and is intended for installation on radiators, manifolds and service panels where regular pressure monitoring is required.

Advantages

The gauge offers a compact 80 mm dial that is easy to read and a robust mechanical design that requires no external power. Its radial G1/2" connection simplifies mounting on many types of heating system components. With accuracy class 2.5, the instrument delivers reliable pressure indications suitable for routine monitoring and basic troubleshooting of boilers and closed-loop circuits.

Suitable for

• Monitoring pressure on radiators and convectors
• Use on manifolds and distribution panels in hydronic heating systems
• Basic pressure checks on boilers and circulation loops
• Replacement of standard mechanical gauges in maintenance tasks

Key specifications

• Dial diameter: 80 mm
• Measuring range: 0–2.5 bar
• Connection type: radial G1/2"
• Instrument type: mechanical pressure gauge
• Accuracy class: 2.5

How to use

Mount the pressure gauge to a compatible G1/2" radial port on the radiator, manifold or service panel using appropriate sealing (for example, PTFE tape or suitable sealing compound) and hand-tighten followed by a controlled wrench turn to avoid over-torquing. Ensure the instrument is positioned so the dial is visible for routine checks. Read the pressure directly from the dial; the pointer indicates the current system pressure within the 0–2.5 bar range. For safety and accuracy, depressurize the system before removing or replacing the gauge.

Usage recommendations

Perform periodic visual checks for signs of leakage or corrosion and verify readings against a calibrated reference gauge if precise measurement is required. Avoid exposing the instrument to vibrations or temperatures outside the manufacturer's recommended operating range to maintain accuracy class 2.5 performance.
