I have an air compressor and a separate air tank. The tank has a standard
gauge and a filler which is like a tire air valve, with a valve stem. You
fill the air tank with a standard air nozzle or a clamp-type nozzle that has
a pin in the middle so that it pushes down the valve stem to let the air in.
The trouble is, the stationary pin in the clamp-type air nozzle that
supplies the air sits too low in the nozzle and doesn't push the valve stem
down. Thus, it doesn't allow air to go through where the valve stem is.
I need a clamp-type nozzle because I am using it to fill an air tank, which
has the standard tire valve-stem to fill the tank. It takes too long to
fill it by holding the nozzle, so you need to do it with the clamp-type.
Sorry to go into so much detail, but the bottom of this kind of nozzle is
the same as the regular non-clamp-type nozzle, but when you add the clamp,
it adds too much space between the stationary pin and the valve stem. I
have bought clamp-type nozzles from Wal-Mart and two auto supply stores in
I did have one that worked, but somehow I lost it and am trying to replace
I have a tank like that. It probably also has a short rubber hose that
connects to the tank, right? Do what I did:
* Remove the hose from the fitting on the tank.
* Install a female quick-connect coupler (Type M is most common) on the
tank in its place.
* Install a male quick-connect fitting on the hose you removed.
At this point, you can use the tank to fill tires with the hose like
before, but you can also connect longer hoses, small air tools, etc.
There's probably already a quick-connect coupler on your air compressor.
If not, install one there too.
Now all you need is a short piece of hose with a male quick-connect
fitting on both ends. (Or you can use a standard male to female
quick-connect hose, plus a short double-male quick-connect). This
allows you to connect the air compressor to the air tank via its
"output" quick connect. Air flows "backwards" just fine through a
normal type M female quick connect coupler.
This way, you ignore the tiny Shrader tire valve, and fill the tank
through a decent-sized fitting.
OK, I did it. It works perfectly, especially the fact that I now have a
decent sized fitting to fill the tank from my compressor.
I hadn't thought of filling it from the output side. That was really
