The Parker Store is where i get my fittings. the parker store i go to is one near my home but there are lots of them.
www.grainger.com has fittings,
ryderfleetproducts has them and on and on.

is a link for the quick release fittings that i have. you just have to match the fitting.
i know push type fittings people are concerned about, i am not so much concerned. that is what they used on the newell to start and on trucks and they are very easy to use. the plastic part does get brittle after 20 years....
