12.7/7.6mm TPV metal fittings, too tight

[MamaKinniku]

I am having trouble tightening the metal fittings, is there any times to doing it without getting pliers and stripping the paint trying to twist it tight? Does it have to be flush?

Do you mean the fitting itself or the compression ring of the fitting? The fitting itself must, of course, be screwed in fully, otherwise it won’t seal. The compression ring doesn’t need to be tightened all the way down.

Yes i meant hte compression ring, its almost impossible without tools to get the compression ring all the way down. It looks like radiators with them have it all the way down but i assume its because its a factory tight thing?

Do you have a picture please?

What tube are you using exactly? Because that looks wrong.

I hope not because it’s the tube the fitting came with , It came with the quick connects should be the tpv 12.7/7.6mm tubing. I bought extra tubing as well, and its the same size.

By “it looks wrong” I meant the picture where the compression ring is sticking out so far.
If all of that is 12.7/7.6 mm TPV tubing, it shouldn’t look like that.
Could you loosen the ring and slide it up? I’d like to see how the tubing sits underneath.

the compression ring barely hits the threads when i push it up but twisting it closer gets harder and harder without something like pliers and a wrench . I tried to get it closer until it gets super hard to turn and almost impossible without tools. Is there an easier way?

Strange. Yes, the compression rings are hard to screw on, but normally you shouldn’t really need a tool for that. The only explanation I can think of is that the tubing simply doesn’t match the exact dimensions, which makes it extremely tight. Unfortunately, I don’t really have any other ideas at the moment either.

well i made sure its the right tubing and its the same tubing that came with the eiswolf 2 as well. I also bought a set of new tubing and its the same with that as well.

Just for anyone looking, the best way i found is to heat the end of it before twisting it tight, thats the easiest way to do it.

I bought multiple sets of tubing and fittings, its all the same. I also have a resin jaw pliers that help out holding it tight without damaging it.
