How to Ensure a Good Seal with Pipe Threads?

What is done with pipe threads to ensure a good seal?

A) Lubricate them B) Tighten them with pliers C) Use thread sealant D) Leave them as is

Answer:

To ensure a good seal with pipe threads, one usually uses thread sealant.

To ensure a good seal with pipe threads, you typically use thread sealant. Thread sealant is a kind of paste which is used to prevent leakage in pipes, valves, and fittings. The sealant fills in the gaps in the threads of pipes and helps create a seal that is tight and leak-proof when the two parts are screwed together. It's not sufficient to only tighten them with pliers or lubricate them because, although these processes might temporarily reduce leakage, they won't provide a long term, water-tight seal.
