Brass threaded extensions are essential components in central heating installations, particularly in steel-based systems. These fittings are frequently used in residential and commercial buildings to connect radiators, boilers and underfloor heating manifolds. Installers working on traditional and modern heating systems often encounter these fittings when extending pipe runs or adapting connections to match system requirements. The 1/2 inch size is a standard dimension in many European heating systems, making it a versatile solution for a wide range of applications.

In boiler installations, the extension is typically used to bridge the gap between the boiler outlet and the primary heating circuit. It is also used in underfloor heating systems to connect manifold branches to the main distribution pipe. The compact design allows for installation in tight spaces, while the brass material ensures resistance to corrosion and thermal expansion. The fitting is suitable for use with both cast iron and steel pipes, and it is compatible with standard heating system pressures and temperatures.

Technical parameters

Weight	0.1 kg
Code	2520036
Brand	IVAR

The extension is sized for 1/2 inch pipe connections, ensuring compatibility with standard heating system components. The brass material provides a balance of strength and corrosion resistance, making it suitable for long-term use in heating systems. The weight of the fitting is 0.1 kg, which is typical for brass fittings of this size. These parameters are essential for correct sizing and selection in heating system design.Installation and connection To install the extension, ensure that the connecting pipes are clean and free from debris. Apply pipe or PTFE tape to the male threads before screwing the fitting into place. The 1/2 inch connection size requires a matching female thread on the adjacent component. After installation, check for leaks by running the system at low pressure and inspecting the connection visually. A common mistake is over-tightening the fitting, which can damage the threads or cause leaks. Always follow the manufacturer's recommended tightening if available.Compatibility and accessories The extension is compatible with standard steel and cast pipes used in central heating systems. It is often used in conjunction with other fittings such as elbows, unions and valves. For a complete installation, additional components such as pipe thread sealant, pipe cutters and pipe wrenches may be required. Installers should also consider the need for insulation or protective coatings in exposed or high- environments.Technical background for designers The extension functions as a mechanical connector in heating systems, allowing for the extension or adaptation of pipe runs. The brass material is chosen for its , strength and resistance to corrosion in wet environments. The design allows for a secure and leak-free connection when properly installed. The fitting is integrated into the system by connecting to adjacent components using standard thread sizes. The service life of the fitting is influenced by the quality of installation, the presence of impurities in the system and the operating temperature and pressure.Service and operation The extension requires minimal maintenance once installed. Regular visual inspections for signs of corrosion or leaks are recommended. If the fitting is part of a system that is frequently shut down or exposed to freezing conditions, additional protective measures such as insulation or antifreeze may be necessary. No scheduled service intervals are specified for this component, but any signs of wear or damage should be addressed promptly to prevent system failure.Frequently asked questions

Can the IVAR 2520036 be used with copper pipes?
Yes, the extension is compatible with copper pipes as long as the thread sizes match. The brass material is suitable for use with copper without causing galvanic corrosion.

Is the extension suitable for use in high-pressure heating systems?
Yes, the extension is designed for use in standard central heating systems. It is suitable for the typical operating pressures encountered in residential and commercial heating installations.

Can the extension be used in underfloor heating systems?
Yes, the extension is commonly used in underfloor heating systems to connect manifold branches to the main distribution pipe. It is suitable for the low-pressure conditions typical of these systems.

What tools are needed to install the extension?
A pipe wrench and a thread sealant applicator are typically required. A pipe cutter may also be needed if the existing pipe length needs to be adjusted before installation.
