Hi, kytnbabe. Welcome to NGA!
Sorry, I don't know anything about quick connectors, other than "try several different kinds of washers". Possibly even order replacement washers directly
from the vendor , though they are likely to gouge you.
Are the leaks from where the connectors click together, or where they clamp onto the hose, or where they screw into the normal hose connectors? I find that a different brand of washers may work better, and cheap washers may be the best ones for some hoses. I just try several.
(Rinse grit off the threads before assembling. IF you tighten with pliers or channel-locks, be very careful not to squeeze hard and create an oval that will never seal tightly. I keep several plastic "female hose thread caps" on hand so any time i don;t have something screwed onto a hose's male threads, I put a cap there, to protect the threads.)
One thing I've done to co-exist with (cheap) problem hoses is to just wrap some heavy plastic film around the leaky spot, and tape or tie it in place, leaving a way for water to dribble or pour out, without spraying all over me as I watered. Now I cut the damaged spot out and splice the hoses with a "hose mender splice", or just make two shorter hoses.
I stopped buying hoses, and now I just cut up the old ones I have into short lengths. Then I add "hose repair fittings" so I have many short lengths of hose.
I ran 3/4" and 1/2" black polyethylene irrigation "mainline" around my yard with a few Y-valves to make "zones". Then I added a hose thread Tee and a shut-off valve (usually a 2-valve Y fitting) EVERYWHERE I might want to water something. And I attach a SHORT length of hose right there, with a hand-sprayer on the end.
Now it's like I have a spigot every single place in the yard where I might once have dragged a hose.
And it's quite CHEAP!

(Plus, I put in some mini-jet sprayers and "Shrubblers" and so on. Now the short hose lengths are just for occasional hand-watering.
I don't really need BOTH omnipresent spigots AND irrigation sprayers on a timer.
It's possible to solve a problem TOO well!
But I like gadgets.
