Adapter Vekolux 3/4" x 1/2"

Product detailed description

This adapter is commonly used in residential and commercial heating systems, particularly in two-pipe direct or angled configurations. It is installed by heating technicians and plumbers to connect radiators or heating units to the central heating system. The adapter ensures a secure and leak-free connection between the Eurocone (EK) and male thread fittings, allowing for efficient heat distribution in buildings with underfloor or panel heating systems.

Its compact design and robust construction make it ideal for use in concealed or tight spaces, where access is limited. The adapter is frequently used in conjunction with KORADO, PURMO, and KORAD radiator bodies, ensuring compatibility with a wide range of existing heating systems. It is important to ensure that the adapter is correctly sized and installed to avoid system inefficiencies or potential leaks.

Technical parameters

Installation and connection

The adapter is installed by connecting the 3/4 inch Eurocone (EK) side to the radiator body and the 1/2 inch male thread side to the pipe or valve. The Eurocone connection requires a matching female Eurocone fitting, while the male thread is tightened using a standard wrench. It is important to apply a suitable sealing compound or tape to the male thread to prevent leaks.

Common installation mistakes include incorrect thread orientation, insufficient tightening, or using incompatible sealing materials. To avoid these issues, always verify the thread type and direction before installation. Ensure that the O-ring is properly seated and undamaged before tightening the connection. After installation, a pressure test should be carried out to confirm the integrity of the connection.

Compatibility and accessories

This adapter is specifically designed for use with KORADO, PURMO, and KORAD radiator bodies. It is not compatible with direct connections to TA, TR, or TP thermostatic valves. When installing, ensure that the Eurocone and male thread fittings are compatible with the adapter's dimensions. Additional components such as sealing tape or compound may be required for a secure connection.

Technical background for designers

The adapter functions as a transition piece between the radiator body and the heating circuit. The EPDM O-ring provides a flexible and durable seal, preventing leakage under varying pressure and temperature conditions.

The adapter is integrated into the system by connecting to the Eurocone fitting on the radiator and the male thread on the pipe or valve. The design allows for efficient heat transfer and minimal pressure drop. The material properties and sealing mechanism contribute to the overall efficiency and longevity of the heating system. Proper sizing and installation are critical to maintaining system performance and preventing premature failure.

Service and operation

During operation, the adapter requires minimal maintenance. It is important to periodically inspect the connection for signs of leakage or corrosion, particularly at the O-ring and thread interface. If any issues are detected, the connection should be disassembled and inspected for wear or damage. The O-ring should be replaced if it shows signs of degradation or hardening.

There are no specific service intervals required for this component. However, during system maintenance or pressure testing, the adapter should be included in the inspection to ensure continued performance. Any damaged or worn parts should be replaced promptly to prevent system inefficiencies or potential failures.

Frequently asked questions

Can this adapter be used with thermostatic valves TA, TR, or TP?
No, this adapter is not suitable for direct connection to thermostatic valves TA, TR, or TP. It is intended for use with radiator bodies only.

What is the maximum operating temperature for this adapter?
The adapter is rated for a maximum operating temperature of +120°C, making it suitable for standard central heating systems.

Is sealing compound required for the male thread connection?
Yes, it is recommended to apply a suitable sealing compound or tape to the male thread to ensure a leak-free connection and prevent loosening over time.

Can this adapter be used in both direct and angled configurations?
Yes, the adapter is suitable for both direct and angled connections in two-pipe heating systems, depending on the installation requirements.
