Quick Connect Couplers: 4 balls or 6?
Posted: Fri Apr 09, 2010 7:36 am
My quick connects are ARO style 3/8" high volume with 6 locking balls.
Harbor Freight stopped selling them.
I need a few more connectors for the Oxygen cylinder conversion or convert to another style.
I can try to locate ARO's or take a short drive to Hf and replace the 3/8" with the more popular 1/4" connectors, usually made with 4 balls.
I have not had any leaks with the ARO units up to 650 psi.
What has been your experience with the 4 ball connectors at 600 psi?
