Pressure gauge - radial, D 63, 0 - 4 bar

Product detailed description

Radial pressure gauges are essential components in the monitoring and control of heating, plumbing and irrigation systems. They are commonly used in residential and commercial buildings to ensure that system pressures remain within safe and operational limits. Installers and service technicians rely on these devices to diagnose issues such as pump performance, pipe blockages or system leaks. The compact 63 mm diameter makes it suitable for installation in tight spaces, such as boiler rooms, pump stations or under sinks.

Correct installation and selection of pressure gauges are crucial for accurate readings and long-term reliability. The pressure range must match the system’s operating conditions, and the connection type must be compatible with the existing piping. This model is designed for use with water-based systems and is not suitable for high-temperature or aggressive media without additional protection.

Installation and connection

This radial pressure gauge features a 1/4 inch male thread for direct connection to standard pipe fittings. The installation should be carried out in a location that is easily accessible for reading and maintenance. Ensure the pipe is clean and free from debris before fitting. Tighten the connection using a wrench to prevent leaks. A common mistake is over-tightening, which can damage the threads or the gauge housing. Always verify the system pressure before installation to ensure it is within the 0–4 bar range of this model.

Compatibility and accessories

This pressure gauge is compatible with standard 1/4 inch threaded connections in heating, plumbing and irrigation systems. It is typically used in conjunction with pressure-reducing valves, expansion vessels or pump controls. No additional accessories are required for standard installation. For larger systems or higher pressure ranges, alternative models with different pressure scales or larger diameters may be necessary.

Technical background for designers

This pressure gauge operates on a mechanical principle, using a Bourdon tube to convert pressure into a linear movement that drives the pointer. The gauge is constructed from durable materials suitable for water-based applications. The 63 mm diameter provides a clear and visible scale for accurate readings. The pressure range of 0–4 bar is suitable for low-pressure systems such as domestic heating and water supply. The gauge should be installed in a stable position to avoid vibration-induced inaccuracies. Long-term performance depends on the quality of the installation and the absence of exposure to excessive vibration or temperature fluctuations.

Service and operation

This pressure gauge requires minimal maintenance. Regular visual inspections should be carried out to ensure the dial is free from damage and the pointer moves smoothly. The connection should be checked for leaks and tightened if necessary. No scheduled service intervals are specified for this model. If the gauge shows erratic readings or fails to return to zero after depressurisation, it should be replaced to ensure accurate monitoring.

Frequently asked questions

Can this pressure gauge be used in a domestic heating system?
Yes, this model is suitable for monitoring pressure in domestic heating systems where the operating pressure is within the 0–4 bar range.

What is the maximum operating pressure for this gauge?
The maximum operating pressure is 4 bar. Exceeding this may cause damage to the internal components.

Is this gauge compatible with 1/4 inch female threaded fittings?
Yes, the 1/4 inch male thread of this gauge allows for direct connection to 1/4 inch female threaded fittings.

Can this model be used for high-temperature water applications?
No, this model is intended for use with water at normal operating temperatures. High-temperature applications require a pressure gauge with appropriate thermal protection.
