I'm tired...

I am hooking up a new 60 gallon vertical air compressor, to a permanent air distribution/regulation system.:) I have now tried 2 hoses between the compressor and the regulator. Each fails to hold pressure at the fitting where the fitting is designed to spin when tightening the fitting. I cant see going and buying another hose, because 2 outa 2 says it'll leak too.

So, I'm looking for advise/source for 5 foot, air hose, preferably with 3/8 NPT fittings, that WONT LEAK.

I'm going for a system that has zero leaks, so it has to pass the soap bubble test!

Any suggestions?

Have you tried to use silicone tape around the threads?

If you have used the tape and the fitting still leaks I would imagine that you have not tightened the hose enough. Just be careful and do not strip any of the threads.
 
The leak is not at the threads. It is at the slip joint that allows the fitting to turn when tightening it (e.g. like your garden hose fitting, where you can turn the fitting with out turning the hose). Soapy bubble test shows the leak "between" the hex on the ntp fitting and the hex on the hose itself.

Don't know what type of hose you have but if I remember correctly mine had male ends on it that did not swivel like a garden hose. They do not turn at all so air hose will twist up when you use it a lot.

Hose

Get a hose with ridgid fittings a shot pipe nipple and a union. Put one end in place then put the nipple and half union on the regulator then the other half union on the hose. Tighten union do soap test.

If it's permanent then why are you using hose?? I have my shop piped with 3/4" copper and I ran it all the way to the compressor, or I should say I STARTED at the compressor and continued on into the shop. I didn't use a union fitting, that's just another place for a leak, and I lose about ten pounds overnight, which I can live with. If I ever need to move my compressor I can just cut the copper and re solder it later. That's why I chose copper, I can easily cut into it and add or subtract fittings as I see fit. The ONLY negative to copper is the cost.
 
Only problem with hardlining copper to the compressor is fatigue cracks from vibration. I have always put a small rubber airline between compressor and manifold system. Any decent airhose will not leak at the swivels....
