iv taken myn to 700psi

also i got some cool QD, even at 700psi i have no problem opening them. idk what they are called, i got them free from work when we had to replace them for higher flow ones

I think I found some good QD couplings...

McMaster:

6537K91

6537K73

ok here are two examples...
The one already attached to the tube is a part (that brass part) I removed from an old water tap ( it had a seal in it already ). Then there is a 1/2" union, a 1/2" to 1/8" bushing and a 1/8" fitting for 4mm OD tubing
(that I use to connect the compressor to the tank and I also use it to connect spudguns to the tank)

The other type is pretty self-explanatory

So does tightening the two 1/2" adapters basically squish the rubber washer very tightly against the compressor outlet tube? Since the squished rubber washer is the only contact point on the tube, wouldn't it be very unstable and not aligned properly?

It works surprisingly well.... wait a second I've been using it on something else as well

ohh I found it

there it is used as a homemade push to connect fitting... back then I didn't have 1/2" to 1/8" bushings

even if it isn't aligned properly it's not a problem...

EDIT
ohh btw there are more compression fittings in that video... the barrel is held in place inside the T by two rubber washers... also the newest version of the semiauto uses one to keep the barrel in place

the key is to compress the washers tightly

So this homeade compression fitting can take 600 PSI?

yes, I still have it on my fridge compressor. And I've never had any problems with it

Ok, thanks... If I can't find one that will fit, I will build this.
