radiator bleed nipple - rounded off

[Vernon]

Have jsut found a radiator upstairs that needs bleeding, but some kind person has rounded off the bleed nipple, is it possible to replace the fitting, or is it a new radiator job? If it is replaceable where would I get one from, I cannot find anything on the internet, but maybe I can get it from a trade counter?

many thanks

part number 6916, 6917, or 6918. Or any of the sheds that have radiators.

parts mentioned above are complete bleed assemblies - which screw into the end of the radiator and, in turn, have a bleed pin screwing down the middle of them. Which one you need depends whether the thread in the end of your radiator is 1/8"BSP, 1/4"BSP or 1/2"BSP.**

If your radiators have integral air vents, you'll just need the pin out of the middle of one of these. With any luck it will have the right thread to fit your rad (many are 2BA) but this is not guaranteed!

** If you're not familiar with British Standard Pipe threads (BSP) the *actual* size is much bigger than the nominal size. Approx diameters are 1/8: 0.383" (~10mm), 1/4: 0.518" (~13mm), 1/2: 0.825" (~21mm)

Thanks guys, at those prices I can afford to order one of each! I had a look around the sheds locally and did not see any, but I will have another look tomorrow.
