You brought up such a good point about how just because a gauge is giving a certain reading doesn’t necessarily mean it’s right. I agree that you should know how to check it to make sure nothing negative happens as a result. If your gauge does end up having an issue it would make a lot of sense to me to find a repair service that specializes in something like that. A precise instrument requires precise care, in my opinion.
Hey Buddy, You need to find mentors to help you. They can be at supply houses, factory reps, guys you work with. Just remember everyone has their own misconceptions. On your existing question: using Nylog on your fittings. Using a dedicated set of vacuum hoses (clean, no oil) goes along way to eliminate problems. As far as fixing the internal vacuum gauge–good luck. just buy a new one at Trutechtools use getschooled for 8% discount.
Is there a good way to vacuum out contaminants without an expensive gauge? Already did nitrogen near test.
