View Full Version : Need Advice on a stripped thread

So a while ago I stripped a thread or two on one of the ports of my trusty old Black Ice Xtreme III Radiator. I overtightened and completely tore out a Bitspower compression fitting. However, I had in my possession old barb fittings with 4 or 5 full threads on it compared to BP's 2, so I used it instead.
Now I am planning on changing cases and would like the fittings to match. Can I use a Bastard file to remove the top two stripped threads, or is there a way to repair the damaged ones?

you can try to re-thread the top and ensure that it will fit the new fittings...

I'd buy a tap. BSPP G1/4 thread. Mcmaster Carr

This might be a stupid suggestion.
But can you use some plumber PTFE tape around the fittings?

Nope. When I stripped the threads it basically destroyed the first two threads. There is nothing for a fitting to latch onto until it is more than two threads deep into the socket.
And I looked into getting a heli-coil kit for fixing the thread, it would cost about as much as it would to buy a whole new rad.
Does anyone have any other ideas before I get a bastard file out and grind the socket down a thread or two?

There are no stupid questions....
Only stupid answers! :)

Grinding down the socket is probably the easiest and cheapest way. Just make sure you get it as flat as possible if you want to use o-rings again. Teflon tape will do the trick otherwise. :)
A tap that size will cost a lot as you noted already, and wont solve your problem if there are no material left to re-thread.
