Pressure Gauge Afriso RF 63 AX Ø63 mm 0–6 bar 1/4" Class 2.5 (model 63513)

The Afriso RF 63 AX Ø63 mm pressure gauge provides a compact mechanical solution for monitoring pressure in heating systems. With a 63 mm diameter dial and a measuring range of 0–6 bar, this instrument is designed for straightforward pressure indication on boilers, heating circuits and associated pipework. The gauge features a 1/4" connection and Class 2.5 accuracy, offering basic, reliable readings for routine checks and maintenance tasks.

Advantages

The instrument's small dial and clear scale enable easy reading in confined installation spaces, while the Class 2.5 accuracy ensures consistent indication suitable for everyday monitoring. Its mechanical design requires no power supply and is resistant to common heating system environments. The 1/4" connection allows direct mounting on standard fittings and valves, simplifying installation and replacement.

Suitable for

• Monitoring pressure on boilers and heating units
• Pressure checks on heating circuits and radiators
• Routine maintenance and system commissioning
• Installation on pipework, valves and manifolds with 1/4" fittings

Key specifications

• Dial diameter: 63 mm
• Measuring range: 0–6 bar
• Connection size: 1/4" (threaded)
• Accuracy class: 2.5
• Mechanism: mechanical Bourdon-type indication
• Mounting: direct connection to pipework or fittings

How to use

Install the pressure gauge on a compatible 1/4" threaded port on the boiler, manifold or pipework, ensuring the connection is clean and sealed with appropriate sealing tape or compound as needed. Position the dial for clear visibility and tighten to the manufacturer's recommended torque to avoid thread damage. Read the pressure value directly from the dial; for system checks, compare readings against expected operating pressures. If the gauge shows signs of damage, leakage or inconsistent readings, replace it to maintain reliable monitoring.

Usage recommendations

Use the gauge within its 0–6 bar range and avoid exposure to pressures beyond that limit. For installations with pulsating or vibration-prone environments, consider mounting arrangements or dampened variants. Periodically verify accuracy during maintenance intervals and replace the gauge if accuracy degradation is suspected.
