Push in airline leak

[walterk]

I tried to find out what the sizes are on these push in quick connects too, but I was not able to get them anywhere. it is possible that different manufacturers use different sizes. I would suggest to use a micrometer and a vernier caliper to measure the dimensions of the original o-ring and try to much them to what you have in your assortment of o-rings box.
It worked for me. They don't have to be 100% the same - slightly bigger will work too.
