An essential component for joining sectional cast iron radiators together. This large joining nipple is approximately 47mm in outer diameter and is double threaded. This means there is a right hand thread on one half and a left hand (reverse) thread on the other side.
If joining together multiple sections of cast iron radiators to create a larger size, you will need to pair this with gaskets for a watertight seal. Please see the fitting guidelines included with your cast iron radiator joining tool for more information.
Large joining nipple: Suitable for all cast iron radiators except the Balmoral range
Small joining nipple: Suitable for the Balmoral range

Perfect
When the joining part that come with the radiator was poor quality, I ordered this and this part is what we used, it fitted the rad perfectly and was a higher quality than the ones that came with the original rad.
