I’m using the non-pro hard tube fittings with 1/2 copper pipe (house plumbing) which has a 15.875mm OD and I have an air leak somewhere. I’ve tested my solder joints and those are good so I’m suspecting that air is leaking past the o-rings. The reason I think it’s the fittings is because I can pull on the tube and it starts to slide out of the fitting when fully tightened.
Has anyone experienced this and if so, did you use the extra o-rings (red/blue/yellow) to get a better seal or was it fine with the black ones? What order did you stack them in? For example: metal collar-plastic collar-red o ring-black o ring.
The o rings in the threaded part of the fittings are in the groove and undamaged if anyone is thinking that the problem is there. I appreciate the help.
