I did a lot of research from reading all these threads and I didn't see a guide and explanation for parts and where to get, so I thought I would do a quick guide and add more as I go along about making a presta tire inflator for air compressor.
First I already had digital Astro pneumatics 3018 tire inflator.
I believe they are made in China if anyone is wondering. I research alot from Joe's racing to longacre and Milton tire inflator. Joes racing never responded to my email...so I ignored them. Milton is made in the USA, but their customer service was clueless about information. Longacre was pricey...so I chose not to make dedicated Presta tire inflator chuck.
The next step is to modify digital tire inflator I already had. From the threads here I got the universal head (air chuck) for both shrader and presta valve. I bought all my items from Amazon. This one is PU9997 universal chuck from problem solvers
I read a lot from other members they cut a hose and attached this hose with the hose clamp that came along with the air chuck. I took the air chuck apart and see that the other thread is similar to 1/4" NPT thread.
So I did my research and saw that the astro 3018's schrader chuck is 1'4" NPT
The PU9997 chuck is also 1/4" NPT thread like...I say like because it's not, but close enough to work at least from my observations. You can see here with the chuck taken apart you have the 1/4" thread.
So up close, you can see 1/4" NPT male thread from the Astro 3018 hose and the 1/4" male thread from the PU9997 chuck. So I got a 1/4" female to 1/4" female hex coupler
Another shot taken far away.
So now I just added some telfon tape for gas and attached the 3 pieces together. No clamp required and completely reversible.
So I removed the original shrader air chuck from Astro 3018 and now I have a universal head for my bike and for my car. I haven't tested the universal head. BTW, the digital tire inflator isn't required. Just get any tire inflator or air control valve that supports 1/4" NPT thread...you have to decide which male or female coupler depending on what kind of tool you have.
I am going to rub tubeless and I had concerns that the tire sealant will gum up the gauges...but I thought I take a chance and I don't have to have two separate inflators. I will already need an optional air fill tool (blow gun) to "pop" the ghetto tubeless tire set up. I had used pencil blow gun...but I wanted a control valve...so I got a milton S153 blow gun.
See next post.
