Unknown air fitting

[alwaysFlOoReD]

I got these in a tool box yard sale buy. What are they used for?
Both have valves.
Both fit my "m" style female coupler.
One screws onto a standard tire air valve.
The other fits one about 2x as big. I haven't seen a schrader valve big enough to screw the fitting on to, including fairly big tractor tires.

Could be hydraulic fittings. Those will have a shutoff on both sides.

Could also be for engine compression testers.

Some companies offer a Schraeder valve option for air couplers.
Some of the larger commercial aircrraft use the larger tire valves.

Can be used for absolutely anything. I have one on my drywall texture gun to shutting off the air instead of having to dis connect the hose all the time.

They are definitely for air.

I have owned several types of compression testers, these don't look like they would work with any of mine.

These have schrader valves same as a tire or efi fuel rail port. But I can't think of a use, hence the question.
Aircraft tires...I'll look next time I'm at the local airport.

The valve I mentioned before is a schrader valve, not an on/off valve.

Thanks for the input.

Currently I'm using one for seating tire beads after manually mounting my tires on rims. I removed the valve from the fitting so there is more airflow. It works but not great, so I doubt that is the intended use. And I just picked up a fitting meant for bead seating...at least it looks like it will work really well. It has little "jaws" that retract when you remove the fitting from the tire stem, and this fitting is screwed directly to the hose - no coupler.

Look like PCL Hi Flow fittings to me!

PCL is the British equivalent of Schraeder, and their regular fittings are very common.

The Hi Flow is a newer fitting, but getting quite common in industrial applications!

.

Yeah, mine looks just like that but shuts off and on.

I had one on my air bubble,was included with it, so that when I disconnected it the pressure wasn’t all lost and no manual valves were necessary. Seals went bad and have replaced with a ball valve, but would love to have more if I could figure out where to purchase them.

I use one to fill my air bubble. Purchased for the purpose.

What's an air bubble?

And where did you buy the fitting?

 

[Lee Celtic]

honda AC has big schrader valves.. looks about the same size.. maybe it's a pressure test adapter or something for car AC..

( ps not my Honda)

 

[seber]

"Air bubble" = portable air tank. I bought the fitting from a pneumatics equipment supplier in Denver during a former life as a machine designer.

 

[landrover bodger]

they look like the fittings we get on airlines from Europe . they get changed to pcl type

Not saying that is what they are, but I have a hooka rig that uses a different kind of hydraulic fitting on them and they are definitely being used for air not hydro...

Took me forever to figure out what they were so I could order spares.

Interesting, I've never seen a "hooka rig", what color is it and and how many "hooka's" does it hold.

Probably not the hooka you're thinking about, but the one I have runs 3 divers to 40'.
