Prestacycle Air Compressor Adapter for CO2 Heads – 6061-T6 Alloy Coupler Plug to Inflate Bike Tires at Home – Compatible with All CO2 Heads, Fits I/M Air Compressor Quick Connectors

This goes form a standard air compressor quick disconnect to any head designed to attach to a threaded C02 cartridge. (bike tire inflator). I used it successfully with both https://smile.amazon.com/gp/product/B01MTVIH3A/ref=ppx_yo_dt_b_asin_title_o01_s00?ie=UTF8&psc=1 And with https://smile.amazon.com/gp/product/B072QB431S/ref=ppx_yo_dt_b_search_asin_title?ie=UTF8&psc=1 the black presta only valve only works with a trigger valve since there is no off switch when used with this adapter.

So what we needed for our new bike shop was an inflator head that would pump up both Schrader and Presta F/V from our compressor. Found a $135 Park tools... THEN we found this li'l hack! Just screwed our tiny double headed CO2 inflator onto this gem and we were in business!

It works. I wish it was just a little bit longer though. So glad they made this. The alternative is a really expensive inflater, or those little crummy twist on convertors.

Great item, works perfectly

Well machined and works fine.
