Hi guys,
I have been using 3/8" Tru-Flate (automotive) quick connects for all the ai=
r hoses in my shop for decades.
I have a bunch of old brass female sleeve lock couplings that require you t=
o move the outer sleeve to connect and disconnect the plug. They are workin=
g fine after decades of use.
I also have a bunch of newer plated steel Tru-flate ones that are push-to-c=
onnect that are supposed to be more convenient, but they are getting increa=
singly difficult to disconnect. I have one that I have to remove all air pr=
essure before it will release the plug.
I have purchased all of these from McMaster-Carr, they are genuine Tru-Flat=
e 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-conn=
ect 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" coup=
lings.
I am attaching a link from McMaster:

-couplings-for-air/
Thank you in advance for any help or information you may have.
Best,
Doug
