Pressure Gauge FERRO M6304R — 63 mm Dial, 1/4” Side Connection

FERRO M6304R — 63 mm Dial, 1/4” Side Connection is a compact mechanical pressure gauge intended for measuring and displaying pressure in fluid and gas systems. The instrument features a 63 mm diameter dial and a lateral 1/4” connection, enabling installation in confined spaces and on panels or pipework where rear connections are not practical. The gauge is suitable for HVAC, plumbing, compressors and general industrial applications requiring a small-format pressure indicator.

Advantages

The gauge provides a clear, easy-to-read 63 mm dial that supports rapid visual monitoring of system pressure. Its 1/4” side connection allows flexible mounting options and simpler retrofit in tight installations. Being a mechanical instrument, it operates without power supply and offers straightforward, low-maintenance operation. The compact form factor enables panel mounting and direct pipe attachment in systems with limited space.

Suitable for

• HVAC systems for monitoring refrigerant and water circuit pressures
• Plumbing and hydronic installations for pressure checks and diagnostics
• Air compressors and pneumatic equipment for system pressure indication
• General industrial machinery and process lines requiring compact pressure indication

Key specifications

• Dial diameter: 63 mm for compact, legible display
• Connection type: side (lateral) 1/4” suitable for tight-space mounting
• Operation: mechanical bourdon-type movement (no electrical supply required)
• Mounting options: panel or direct pipe/line connection using side port
• Intended media: compatible with fluids and gases used in HVAC, plumbing and industrial systems

How to use

Install the gauge by securing the body to the panel or connecting the 1/4” side port to the pressure line using appropriate fittings and sealant. Ensure the connection is tightened to the manufacturer's recommended torque and that the gauge face is oriented for easy reading. Before pressurizing the system, verify that the gauge range matches the expected operating pressures. After installation, pressurize the system gradually and check for leaks at the connection. Periodically inspect the gauge for mechanical damage, zero offset, and dirt on the dial glass to ensure reliable readings.

Usage recommendations

Use the FERRO 63 mm side-connection pressure gauge in systems where space constraints or panel layouts favor lateral ports. Select a gauge range slightly above the maximum system pressure for accurate readings and avoid exposing the instrument to pressures beyond its rated range. For prolonged service life, protect the gauge from strong vibrations, corrosive media and extreme temperatures; consider using isolating valves or dampeners where necessary.
