 Outlet size: 1/2"
 Function: threaded reducer for radiator valve connection

How to use
Ensure the mating surfaces and threads on both the radiator valve and pipe fitting are clean and free of debris. Wrap appropriate thread sealant tape or apply a compatible thread sealant to the smaller thread as recommended for your system. Screw the adapter into the larger valve thread by hand to start, then tighten with an appropriate wrench until secure, taking care not to overtighten and damage the threads. After installation, pressurize the system and inspect the connection for leaks; retighten slightly if necessary following manufacturer guidelines for sealing materials.
Usage recommendations
Use compatible sealing materials (PTFE tape or liquid thread sealant) rated for heating systems. Avoid excessive torque to prevent thread damage. Verify material compatibility with the medium and operating temperatures of your heating system before installation.
