Radiator FIller/Bleed D1 Size/Thread

[cookiesa]

I am trying to source a blank to replace this in my radiator (D1 300tdi) Does anyone know what size/thread these are so I can try to source a blank to tap?

$10 or so will get you the brass plug from a LR spares shop.

IIRC it's 1/2" BSP, so a brass plug from the plumbing supplies fit, just go easy when using a taper plug as I'm pretty sure the threads are parallel. (it's all I used, with a few wraps of thread tape)

When I took my brass plug into some plumber's supplies they all gave me a dumb look and, I tried Reece, Tradelink and a couple of others with no luck

Thanks everyone for your help... as someone who has no real knowledge of these differences in threads... can someone please xplain the difference between the tapered and parellel

easy...

draw a square. the sides that go up and down are parallel to each other.

draw an isosceles triangle with the point uppermost and the odd side at the bottom. rule off the top 1/3. the sides on the new shape are tapered.

now imagine your 2 shapes as a side profile of a cylindrical shape and add a thread.

Taper pipe threads seal on the threads generally with the aid of some hemp, or teflon tape, or pipe sealant. Parallel pipe threads are for mechanical fastening and need an o-ring, or copper or fibre washer or similar to seal against a shoulder.
