thread mismatch?

hi thanks for having me, new member here.
I have an air compressor and think the hose fitting is not right for the valve in which I am suppose to thread into. it seems to walk a little to much as I spin it in. anyone able to tell from the pic if its correct and im crazy or if it is actually wrong? thanks in advance.

1.This would typically be a pipe thread in my opinion but with the O-Ring I wonder.
2. Have you tried known pipe threads on each to see what they are?
3. Plenty Teflon tape might make it stable or add the needed metal adapter to one or the other or both.

Judging by the recessed area before the threads start I'm thinking it requires an adapter that is straight thread with an o-ring on one end and pipe thread on the other

right on, i went and got some fittings at Home Depot. I also picked up some heavy duty teflon tape and loctite red. I've got it together but cant get the orange hose/fitting to not leak ... a little but still it leaks (soap bubble test)

1. Is it a new compressor? If so, it needs to go back as defected (poor machined threads or etc).

2. If itís new a parts list should ID the types of threads.


3. If itís used, you possibly need to cut a good set of threads at the regulator or etc.. If the dept and wall thickness will allow which I doubt. Which means a good reduced adapter should be sealed into the female threads.

4. Is the o-ring not firm enough? It appears it would seal a leak if seated good (with a washer between fitting and o-rind). Good Luck!

Hi,
It is/was a new compressor. In fact this is the second one.

There are no parts lists within the packaging, I would need to contact the compressor supplier for that.

the o-ring seems too small, and when it is right up against the nut of the fitting it doesnt seem to seal properly like that. I think your right that a washer would help and be the right way to do it. ty

Your adapter fitting has to be male npt on one end and female SAE oring on the other.
SAE+4F+TO+1+4+NPTM+CONNECTOR_M.jpg

also looks like the oring needs replaced.

this is what I was able to come up with:



the leaking has drastically reduced, in about 5 hours I have lost about 4psi. I added a quick disconnect for a blow tool. Soapy bubbles show only the orange hose fitting leaking, I guess I will try to replace the o-ring. thanks

  • Using the Brass vs Gal T length wise makes me wonder if that is a weakness vs using opposites outlets. Keeping the T closer to the regulator to prevent weakness (relating to bumping and breaking). An Opinion, LOL!
  • Is the leak hose to fitting and a hose clamp could solve or fitting to fitting? I run my compressor on a timer to try and make sure itís off vs a leak causing it to run while it is not in use.
  • Quality Is Becoming A Challenge Due To Competitive Rates. I hope it will serve your needs.
