## Long description

Sourcing straight radiator connection 3/4" R387X002 is a plumbing fitting designed to create a secure threaded link between a radiator valve and the heating pipework. The fitting provides a straight connection with a 3/4" thread size suitable for hot-water central heating systems in residential and light commercial installations.

Advantages
The fitting offers a reliable threaded joint that simplifies radiator installation and replacement without altering the pipe layout. Its straight design minimizes flow disturbance while providing mechanical stability at the connection point. Manufactured to common plumbing standards, the component is compatible with typical radiator valves and copper or steel piping systems used in hot-water heating circuits.
Suitable for
 Connecting radiators to hot-water central heating pipework with a 3/4" threaded interface
 Replacement of damaged or corroded straight radiator connections
 Installation in residential apartments, houses, and small commercial heating systems
 Situations requiring a compact inline threaded coupling between valve and pipe
Key specifications
 Connection type: straight threaded radiator connection
 Thread size: 3/4" (straight)
 Application: hot-water central heating systems
 Compatibility: standard radiator valves and common heating pipes (copper, steel)
 Form factor: compact inline fitting for direct valve-to-pipe assembly
How to use
Shut off the heating system and drain the section of the circuit where the fitting will be installed. Ensure mating threads on the radiator valve and pipe are clean and free of debris. Apply an appropriate thread sealant or PTFE tape to the male threads if required by the system. Hand-start the fitting onto the mating thread, then tighten using a suitable wrench until a secure, leak-free joint is achieved without over-tightening. Refill and pressurize the system, then inspect the joint for leaks during initial operation.
Usage recommendations
Use a compatible thread sealant rated for heating systems and follow local plumbing codes. Verify material compatibility with the existing pipework to prevent galvanic corrosion. If unsure about installation or system isolation, consult a qualified heating engineer.
