Just over hand tight imho not much more than that me thinks

Did mine on the chim recently (swirl pot but still alloy). Turned by hand until it wouldnt go any further then a half turn further with a spanner was all thats needed. Maybe half a turn was more than it needed at that as it didnt leak when finger tight.

ummm strange as done it up to 10 lb/ft and it was leaking, had to do it to 25lb/ft before it stopped.
I think that was less that 1/2 a turn though

I was testing it with 20 psi air, maybe with water it don't have to be as tight.

Just hope I don't have to take it out again.

Thanks
Leigh

Was that assembled dry? A smear of Hylomar blue will help it seal with much less torque.

It was dry. it had a ali crush washer so thought it would not need extra sealant. the thread on the rad must have had a 8mm welded wall on it, so was not to worried about doing it tight ish. plus its a big nut. would not have wanted to go much more though.

I will use some blue though if I ever take it off again, hopfully not though.

Thanks again GV8
