Thread type on central heating element.

Rampage · 8 Jan 2015

Hi, does any know the thread type, minor diameter and pitch of the thread on the heating elements that screw into a central heating cylinder?
I need to make a email fitting for one to screw into.

Thanks,

Is it 2.25" BSP ?
I've just found some cheap flanges on eBay that would save a lot of time if they are the correct thread!

2.25" is the norm.

So this would fit it?

Yes. It used to be common practice to "Wipe" one of those onto a cylinder.

Ok, thanks!
