JACO Bike Presta Valve Tire Air Chuck - 1/4" NPT (Pack of 2) (Open Flow)

Can't believe I wasted time and money on other, "proprietary" Presta inflator fittings...this is exactly what you need if you already have a tire inflator (or just a pneumatic ball valve) and just want to be able to use your air compressor and industry-standard pneumatic fittings, without having to buy a whole second inflator. With this fitting, I can go back and forth between Presta and Schrader inflators with one simple, standard quick disconnect!

Like these presta valve adapters. Works great on my air compressor to fill all sorts of bike tires.

Internal diameter is too small and restricts air flow into tire. Using a very large air compressor. Used dish soap and water to help lubricate tire.UPDATE: if you remove the metal reducer in the middle it allow greater air volume.

connected to compressor hose. Had to use an old hose line and connected this gem. I use the air compressor to pump my 29" tubeless in seconds with the needed pressure to inflate. What a find.

Complete piece of garbage both leak totally useless for $12 they went directly in the trash. Do not waste your money. I Purchased, a high dollar part tool, which is what I should’ve done from the beginning.

I have been looking for something simple like this for a while. Previously used the schraeder to presta adapters which screw onto the presta valve, but it made it more of a pain for a simple inflate before a bike ride. With this I was able to unscrew the schraeder attachment on my air compressor tire inflator, screw this attachment on and cut the time for a quick tire top off by a huge amount. Definitely a great purchase for me.

Works great, fits a standard compressor hose fitting, inexpensive...yes the thing is ugly but I love it.I had previously bought a more expensive prestacycle one which looked pretty but turned out to be garbage.

I had high hopes for these. But they are just ok. Leak air and are not very well made for the price. Why do they only come in packs of two is probably because the quality standards are so low. Out of the two one works ok and the other is just a leaking pain. I don’t know why it’s so hard to find a decent presta inflator head. I use my air compressor and need something that allows the gauge on my tire inflator to read the pressure. These do that but not worth it at this price. Those cheap screw on things that allow you to just use a regular inflator don’t hold the presta valve open to take a pressure reading.Really why only a pack of two. They come in a tiny generic box. The quality shows they mass produced these and don’t care how they come out. The metal has all kinds of tool marks and the finish is just terrible. The other offerings from this company for presta valves is $30 bucks and only come in packs of 2. What a rip off… needless to say these are going back.
