Threaded coolant hose leaking...what to seal the threads with?

Works way better than thread tape....also helps with disassembly later

 

Wierd.

I've never had any luck with the paste.
I always use the tape. Never had a leak.

But yes . Pipe thread always requires some sort of sealer before threading together.

 

I've used both tape & paste, both work. Gotta be careful not to over tighten, especially if threading into brass or aluminum, it'll split and leak. As far as adding a pipe for something, I'd go with stainless, won't corrode or rust, or maybe brass...

 

It's all I have ever used...thing about reviews is you have to ask if the person writing it was smart enough to use the product to begin with. Whether you use paste or tape the threads inside and out must be absolutely clean....that's where most fall short

 

@wore out is correct that it needs to be clean. Quick trip over wire wheel does wonders.

Now this is all I have ever used. But it's more the TFE. The stuff from you house hold supply story dont normally have it and is for stationary house hold water pipes. The junk that never dries.



Added, never leave the lid off, and never leave a bottle of it between your drives while working. Unless you like cleaning up a huge fricken mess. It was the hugh bottle, not 4oz..

 

We use this stuff.

 

Some those brass ones will snap off at a bad time while driving, use gal. steel or stainless if you can find one in that size?
