I am looking for pneumatic couplers like these for a 1/2 inch air hose (for a train horn).

Where can i find these (preferably locally)?

 

I haven't had much luck find those locally. A couple of ideas would be high end computer stores, those fittings are used in water cooling processors. Maybe aquarium stores.

If you get in desperate need, you can use brass ferrule fittings. Ace hardware, lowes, home depot should have something that will work for you. You might look there anyway, say in the irrigation section.

 

Ace and Home Depot only had Shark Bites for copper tubing and pvc tubing. The guy said it would not work for irrigation hoses.

 

Try McMaster-Carr. LINK

 

They are also available a heavy truck part houses; they are used in air brake assemblies and other pneumatic systems.Iget mine locally.

 

McMaster Carr, Grainger, Festo

 

Truck parts place, like stated above, should have them for d.o.t. airbrake systems. Running d.o.t. tubing is a good idea as it is rated for service brakes at a wide range of temps.

 

think about PEX fittings ? I don't know if they make what you pictured in 1/2 inch ?
but pex does and it has all kinds of fittings

 

Any truck shop/stop , and any Napa store . If you have a air ride supplier dealer in your area . Pretty commen air fitting .

 

He's looking for 1/2 id those aren't common IMHO

 

 

Good to know
Thanks
I have not seen the larger stuff
