Hi guys,
I have been using 3/8" Tru-Flate (automotive) quick connects for all the
air hoses in my shop for decades.
I have a bunch of old brass female sleeve lock couplings that require you
to move the outer sleeve to connect and disconnect the plug. They are
working fine after decades of use.
I also have a bunch of newer plated steel Tru-flate ones that are
push-to-connect that are supposed to be more convenient, but they are
getting increasingly difficult to disconnect. I have one that I have to
remove all air pressure before it will release the plug.
I have purchased all of these from McMaster-Carr, they are genuine
Tru-Flate products.
I have tried lubricating them, but it does not seem to help.
I also have tried to find new Tru-Flate connectors without the
push-to-connect feature, but cannot locate them for 1/4" pipe and 3/8"
coupling.
Do any of you have experience with this problem? It is quite annoying when
you want to change a tool, as you might imagine.
I have seen some universal sleeve lock couplings that are supposed to work
with Tru-Flate plugs, but I have not seen them with 1/4" pipe and 3/8"
couplings.
I am attaching a link from McMaster:

Thank you in advance for any help or information you may have.
Best,
Doug
