Radiator valve connector Schuller 20003, 2-piece set for 12 mm radiator pipe

Two-piece radiator valve connector set Schuller 20003 is designed to link radiator valves or controllers to 12 mm metal radiator pipe. The set provides a mechanical coupling that ensures a secure transition between the valve body and the pipe, suitable for installation or replacement in domestic heating systems where a 12 mm interface is required.

Advantages

The two-piece construction allows straightforward assembly and alignment during installation. Manufactured to fit 12 mm radiator pipe, the connector set provides a compact connection that minimizes space between the valve and the pipe. The design facilitates reliable mechanical contact and reduces the risk of leaks when installed correctly with compatible valves and proper sealing.

Suitable for

• Connecting radiator valves or thermostatic heads to 12 mm radiator pipe
• Replacement of existing radiator connectors in domestic heating systems
• DIY heating repairs and professional radiator installations requiring a 12 mm interface

Key specifications

• Configuration: 2-piece connector set
• Pipe size compatibility: 12 mm metal radiator pipe
• Function: mechanical coupling between valve/controller and pipe
• Application area: domestic radiator/heating systems

How to use

Shut off the heating system and drain the radiator or the relevant section of the piping before starting work. Remove the old connector if present, clean the pipe end, and check for burrs or damage. Position the connector pieces according to the valve manufacturer's instructions and slide them onto the 12 mm pipe. Assemble the valve or controller to the connector, ensuring correct alignment and engagement. Apply the recommended sealing method (such as compression fittings, olive, or compatible sealing tape) as required by the valve and local plumbing practice. After assembly, refill and pressurize the system, then inspect the connection for leaks and proper operation.

Usage recommendations

Use this connector set only with compatible 12 mm radiator pipes and valves. Follow valve manufacturer installation instructions and local plumbing codes. If unsure about sealing method or compatibility, consult a qualified heating technician to ensure leak-free and safe operation.
