How To Repair A Broken Radiator Nipple

Hi the bleed nipple sheared off on a double radiator - see motion picture.
I'grand really annoyed I didn't spray some wd-40 in there to encounter if it would gratis information technology up. Hindsight eh!
I wondered if it is possible to repair it. Peradventure try to advisedly drill out the broken nipple with a small drill bit. Is this possible? Are new drain nipples available ?

Could I somehow tap a new valve?

Thanks.

sometimes if you use a left-paw drill, the torque and vibration will go information technology out
However you must be careful of contumely swarf falling within the radiator equally it causes pin-hole corrosion

I run across no screwed plug in your rad. Is at that place anything at the other end?
If y'all have a dremmel or similar perhaps you could, at a pinch, score a line across what is left and then a slot-head screwdriver might grip it? Just an idea...
I figured if I drill information technology, I should probably take the rad off so I tin flush any $.25 of filings. I'm non sure what you mean by spiral plug. The other end looks exactly the aforementioned, but minus the drain valve i.eastward. it'south just blank.
Interesting idea, I don't accept the tool to do that, merely maybe it's possible.
most radiators have a steel plug screwed into the cease, that the bleed pivot screws into, and in this instance you can remove the unabridged plug and fit a new one. Yours does not appear to accept them, and then the job is more than difficult.
if it was so tight that it sheared off, its unlikey a screwdriver will unscrew information technology.

Its easy enough to get a drill which is known as the tapping drill size for the relevant thread size which I think is 1/eight" BSP.
When y'all have drilled it out the you employ a plug tap to retap information technology.

Simply the tapping simply goes in a short distance to a reduced size "cone" confronting which the original screw creates a valve.

If y'all were clever you could recreate this only if not its easy to create a plug bolt with a PTFE tape seal on the threads.

screwfix, new radiator?
Yes why mess around. Your time is surely worth something to you lot. New rad.
Personally I'd probably get a new radiator, the fact that'due south rusted so solid suggests the inside is probably in a similar condition
If you want to try getting it out, drill a pilot pigsty then endeavour a spiral extractor on it?
5.5mm drill dead centre or new rad.
Dremil wont work will slot rad before you slot nipple.
Drill hole on acme, air out, screw in, not hard, but get help if your unsure, Picket everything they practise, as they hate that,
Dont be a joker
