QuestionsCategory: QuestionsPipe union fitting leaks slowly. How to seal?
Handyman Staff asked 3 weeks ago

Newbie to plumbing. I have this pipe fitting that is leaking very slowly through the top of the hex nut. I tried to tighten the hex nut with a pipe wrench but it didn't help.

I'm in the US. The pipe diameter is about 1 inch.

What is this type of fitting called?

How do I seal this fitting properly?
