Pressure Gauge Afriso RF 63 AX Ø63 mm 0–6 bar 1/2" Class 2.5 - model 63538

The Afriso RF 63 AX pressure gauge with a 63 mm dial and a 0–6 bar measuring range provides straightforward mechanical pressure indication for heating, plumbing and hydronic systems. Designed for basic monitoring tasks, this compact instrument features a 1/2" connection and an accuracy class of 2.5, making it suitable for visible pressure checks on boilers, pumps and distribution loops. The Ø63 mm housing allows mounting in panels or directly on pipes where space is limited and a clear analogue reading is required.

Advantages

The gauge delivers a simple, reliable pressure display without the need for power. Its compact diameter and standard 1/2" connection enable easy replacement or installation in existing systems. Class 2.5 accuracy balances affordability with sufficient precision for everyday monitoring in residential and light commercial heating and plumbing applications. The analog dial is easy to read at a glance, and the robust mechanical design is suitable for routine operation in technical rooms and service environments.

Suitable for

• Pressure checks on boilers and water heaters
• Monitoring pump discharge and suction lines
• Hydronic heating system distribution loops
• Plumbing installations and service panels

Key specifications

• Dial diameter: 63 mm
• Measuring range: 0–6 bar
• Connection: 1/2" (standard threaded connection)
• Accuracy class: 2.5
• Display type: Analog pointer dial
• Mounting: Panel or direct pipe/bracket mounting (compact housing)

How to use

Install the pressure gauge by sealing the 1/2" threaded connection into the designated port on the boiler, pump or pipe tee. Ensure the connection is tight and leak-free using appropriate thread sealant or tape rated for the system fluid. Position the dial so it is clearly visible for routine checks; the compact Ø63 mm housing allows fitting into confined panels. Read the pressure value directly from the analog pointer; the 0–6 bar scale provides a quick indication of system pressure. For safety, depressurize the system before removal or replacement of the instrument.

Usage recommendations

Verify compatibility with the system fluid and operating temperature. For increased measurement reliability, avoid installing the gauge where it is exposed to strong vibrations or direct heat sources. Periodically check the dial for mechanical damage and accuracy drift in line with routine maintenance schedules; replace if the pointer sticks or readings become inconsistent.
