Good day RV guys.
Can anyone please tell me how deep I need to thread the national pipe thread in to ensure a good seal. I can turn a NPT fitting by hand about 3 full turns. After that it becomes quite tight. I am "thinking" another two full turns( hopefully the fitting won't snap before that ) Obviously I would be using Permatex 2 as a sealant, but just wondering how deep I need to thread these guys in to ensure a good seal.
