Pressure gauge FERRO M6306R radial 63 mm dial 1/4" 0–6 bar side connection

FERRO M6306R radial 63 mm pressure gauge with a 1/4" side connection is designed to provide a clear analog indication of fluid or gas pressure in industrial and HVAC systems. The instrument features a 63 mm diameter dial calibrated for 0–6 bar, a radial (front-facing) readout and a side-mounted female connection that allows compact panel or pipe installation. Its mechanical movement gives direct pressure measurement without electronics, making it suitable for continuous monitoring of system pressure.

Advantages

The gauge offers a compact form factor and a readable 63 mm dial that supports quick visual checks of system pressure. A side-mounted 1/4" female connection enables flexible installation in confined spaces or on manifolds. The simple mechanical construction ensures reliable operation in typical HVAC and industrial environments, providing stable readings within the 0–6 bar range without need for power.

Suitable for

• Monitoring water and heating systems in residential and commercial HVAC installations
• Pressure checks on boilers, pumps and circulators
• Industrial process lines with pressures up to 6 bar
• Panel or pipe-mounted pressure indication where compact gauges are required

Key specifications

• Dial diameter: 63 mm
• Pressure range: 0–6 bar
• Connection type: female 1/4" side connection
• Display type: analog radial dial
• Mounting: panel or pipe installation compatible with side connection
• Operation: mechanical movement (no electrical power required)

How to use

Install the gauge by screwing the 1/4" female side connection onto the appropriate male thread on the pipe, manifold or adapter, ensuring correct sealing with suitable tape or sealant. Position the gauge so the radial dial is visible for reading and avoid overtightening to prevent damage to threads. After installation, pressurize the system gradually and observe the needle movement to confirm correct operation and that readings remain within the 0–6 bar scale. Periodically inspect for leaks and mechanical damage.

Usage recommendations

Use the gauge within its specified 0–6 bar range and avoid exposing it to pressures above the maximum rating. Install on compatible threaded fittings and protect from strong vibrations and corrosive media. For accurate readings in critical applications, consider regular calibration checks and replace the gauge if the needle sticks or shows inconsistent movement.
