## Description

The AstroAI Closed Flow Air Chuck fits most inflators, but is designed specifically for use with AstroAI tire inflator gauges. The brass chuck design inflates tires easily, even on heavy-duty work vehicles thanks to a 250 PSI maximum pressure rating. There's no need to thread the chuck to valve stems, because a locking clip securely seals the air chuck into place on a valve stem. A straight tip makes inflation hassle free. Package Content: 2 x AstroAI Air Chuck

- 250 PSI RATED BRASS COMPONENTS are designed for heavy-duty use with tire inflators and gauges
- COMPATIBLE WITH SCHRADER valves; the closed flow design allows air to flow when the internal flow valve is open

- HEAVY DUTY STRAIGHT TIP makes filling tire hassle-free; the locking clip keeps the chuck attached to the valve stem during inflation

## Questions & Answers

**Q: What is the difference, open flow and closed flow?**
A: Lot's of info here that may confuse most.  Open flow for hand held tire inflators or small 12v pumps.  Allows the air to flow both directions, aka if your inflator has a pressure gauge and manual valve to let the air out of the hose.  

Closed flow is for direct connect to a compressor where you want the air to stop when you disconnect it, as in a shop or gas station.

Both open the valve step to allow the air to flow.

**Q: will this work on presta valves?**
A: no from what i read you would need an adepter

**Q: Im filling air tanks. Will i have to hold lever down or will it lock in open position?**
A: If you are filling via a Schrader valve you will have to lock it  on the valve otherwise it will not fit on the valve. Once on the valve you do not have to hold it down..  It least that has been my experience.  I have been pleased with how these work.  I bought mine to  use on a Jaco inflator tool after the Jaco chuck failed.    Not sure how it would hold up under commercial  use.  I use mine around the shop maintaining lawn equipment and personal vehicle tires for the last year

**Q: I am making a harness to deflate/inflate all 4 tires simultaneously.  When I connect the first one to a valve stem, are the other 3 closed, or leak?**
A: They should only flow (to deflate/inflate) when they are engaged to a valve. If you scroll down on the photos, they actually have one that describes open vs closed. My first purchase I didn't pay enough attention and order "open" ones and they leaked thru.  Then I ordered the closed ones and they have worked great since.
