## Summary description

FERRO M6304R is a mechanical pressure gauge with a 63 mm dial and a 1/4” side (lateral) connection. Designed to measure and display pressure in fluid or gas systems, it provides compact installation where side mounting is required. Suitable for HVAC, plumbing, compressors and general industrial applications that need a small-format, panel- or pipe-mounted pressure indicator.

## Long description

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.
