[Shop-talk] air hose quick disconnects that don't leak

[Mark Andy]

Howdy,

Recommendations for air hose quick disconnect fittings that don't leak?

I have the standard brass & 'other material' type ones from Lowes/HD/HF
like these:

Problem is that fairly quickly they start to leak when connected and I'm
getting sick of it.  Are there versions of these things that are more
robust?

Thanks!

Mark
