Ensure your new radiators are compatible with your existing pipework. This is a replacement reducing bush end with a conventional parallel thread, which means a right hand turn will tighten and a left hand turn will loosen. This replacement bush end is suitable for all of our radiator styles except for the Balmoral range.
This reducing bush end connects conventional 1.5” pipework with our 0.5” BSP radiators. This is designed to be sited below the blank bush end. Available in a range of bespoke radiator colours for a perfect match. You’ll need to pair this with a gasket and PTFE tape to create a watertight seal. Please see our fitting guidelines for more information.
Please note: This radiator bush end is not compatible with our Balmoral style radiator. Please confirm the radiator style before ordering.

Item as described and worked very well, delivered quickly, Thanks
Brett Griffiths verified owner
The product was perfect for the job, but what was really impressive and noteworthy was the attitude of the staff who went above and beyond to sort me out and very quickly send the part I needed. I probably should have discussed it with them at the beginning, but they were there for me to pick up the pieces.
Charles Johnson verified owner

Reducing Bush
Cannot thank Cast Iron Radiators enough for their product and advice. I needed a slightly different size for radiator and Steve couldn’t have been more helpful in suggesting the correct one. Arrived quickly and fits perfectly! Great price too! 10/10!!
Drew verified owner
Exceptional, personal service
Big thanks to the cast iron radiator team.
I ordered the wrong size spare lug nut. I called up, explained my mistake, I was then given proper instructions on how to measure the thread.
To my absolute surprise they decided to send me a new one free of charge. These guys will be my go-to from now on. Big thanks!
