This made the job complete, an excellent piece of kit.
Yep, as described and did the trick 👍 (adding this bit to make the minimum word count 🤪)
handy when you need extra length due to the pipe centre being off
They dont work under 20 mm as there's not enough internal thread length to screw radiator tail in to
Just the job when replacing imperial radiators with metric ones and you don't want to move the pipes. It screws into the radiator and the valve spigot screws into this. The female thread on the 10mm ones are a bit short but the 20mm style is great. Nice chrome finish as well.
