Pressure Gauge Afriso RF 100 RAD 100 mm 0–16 bar 1/2" for Heating Systems

The Afriso RF 100 RAD is an analogue pressure gauge designed for heating systems, featuring a 100 mm diameter dial and a measuring range of 0–16 bar. With a 1/2" threaded connection, this gauge is intended for monitoring boiler, radiator and central heating circuit pressures. The clear scale and durable housing provide reliable indication of system pressure during installation, routine checks and maintenance.

Advantages

The instrument offers a large, easily readable 100 mm dial that improves visibility in technical and confined spaces. Its 0–16 bar range covers the typical operating pressures of residential and light commercial heating systems. The 1/2" connection is compatible with common fittings used on boilers and radiators. Mechanical construction ensures a simple, low-maintenance device with immediate analogue feedback without the need for power.

Suitable for

• Monitoring pressure in domestic and small commercial boilers
• Installation on radiators and heating manifolds
• Use in central heating circuits and hydronic systems
• Routine maintenance and system pressure checks

Key specifications

• Dial diameter: 100 mm
• Measuring range: 0–16 bar
• Connection size and type: 1/2" threaded
• Display type: analogue pressure dial with clear scale
• Application: heating systems (boilers, radiators, central heating)

How to use

Mount the gauge to a compatible 1/2" female threaded port on the boiler, manifold or radiator connection point. Ensure the system is depressurised before installation to avoid personal injury and damage to the gauge. Tighten the connection with appropriate sealing material (e.g., PTFE tape) and a suitable wrench without over-torquing. After installation, pressurise the system and observe the dial to verify normal operating pressure within the 0–16 bar range. Use the gauge for periodic visual checks and during commissioning or maintenance operations.

Usage recommendations

Install the gauge where the dial is visible and protected from mechanical damage and direct heat. Avoid exposing the instrument to corrosive fluids or prolonged vibration. For accuracy, compare readings with a calibrated reference instrument during system commissioning and replace the gauge if the pointer sticks, shows erratic movement, or the glass is damaged.
