Pressure gauge Afriso RF 63 axial, Ø63 mm, 0–2.5 bar, G1/4" axial, accuracy class 2.5

The Afriso RF 63 axial pressure gauge is a compact instrument with a 63 mm diameter dial designed for measuring low pressures up to 2.5 bar. Fitted with an axial G1/4" connection and accuracy class 2.5, this gauge is intended for monitoring pressure in heating and hydronic systems where an axial mounting orientation is required. The clear scale and robust casing allow installation on panels or pipelines to provide continuous indication of system pressure in boilers, radiators and circulation circuits.

Advantages

The dial size and axial G1/4" connection make this gauge suitable for confined installation spaces and panel mounting. Accuracy class 2.5 provides dependable readings for general monitoring and system checks. The compact construction simplifies replacement or retrofit in existing heating and hydronic installations. Corrosion-resistant materials and a sealed case ensure stable operation in typical indoor mechanical environments.

Suitable for

• Monitoring pressure in domestic and commercial heating systems
• Installation on boiler fronts, manifolds or control panels with axial connection
• Pressure indication in radiators, circulation pumps and closed hydronic circuits

Key specifications

• Dial diameter: 63 mm
• Measuring range: 0–2.5 bar
• Connection type and orientation: G1/4" axial
• Accuracy class: 2.5
• Mounting options: panel or pipe with axial connection

How to use

Select an installation point compatible with axial G1/4" connection and ensure the system is depressurized before fitting. Screw the pressure gauge into the threaded connection by hand and tighten with an appropriate tool without over-torquing to avoid damage to the case or thread. Position the dial so it is visible from the operator position. After installation, pressurize the system and verify the gauge reads within expected range and shows no leaks at the connection. Regularly inspect the gauge for mechanical damage and signs of corrosion.

Usage recommendations

Install the gauge where it is protected from direct impact, excessive vibration and weather exposure. For improved longevity, fit an isolating valve or siphon on systems with hot media and perform periodic calibration checks to confirm continued accuracy class 2.5 performance.
