Adapter for Shop Air to Manifold Gauges
Posted: Tue Aug 12, 2025 3:31 pm
I need to pressure test a sealed system to find a leak. Problem is, I can't find the correct fittings to hook up shop air (or a bottle of nitrogen) to my manifold gauges. The former is a typical 3/8-in by 18tpi male NPT fitting; the latter uses male ACME thread. (Picture the threaded connector on a bottle of r124 refrigerant here.)
I've asked two different AC techs I happened upon at a Home Depot parking lot this question, but neither had a clue.
Anyone have any idea where I can buy this sort of adapter?
