Clean 😎👊🏼💯 Using the Pipe Vise Thread Sealant. It’s anaerobic, that means once in the threads and tightened the lack of oxygen allows it to cure and seal the thread path from leaks. It can be undone, it’s typically a little harder to disassemble joints that have this type of sealant but it’s not difficult. @pipevise sent me a couple tubes to sample, I’ve used it so far on three boiler installs. Both for gas pipe and water pipe. Copper/brass, stainless steel and also black iron pipe threads.
