Review: Just what I needed. - Needed this for our Motorhome with dual wheels on the rear axle. Original fitting that came with it was angled and would not go through the outer wheel to reach the inner wheel. This is a straight line fitting, which works perfectly. Well built, solid.
Review: This is a great air chuck for all these reasons - First, I found myself in an interesting situation after purchasing and installing MagBak RimCase for my Tesla Model Y. The RimCase has hols cut for the valve stems, however, they are very small. So small in fact, that the locking air chuck I had wouldn’t fit. So, I needed something smaller. After doing so research, I chose this option and here are the several reasons why. First, Milton is a reputable company that has been around for quite some time so I have some level of confidence I could trust and expect the chuck to work. Also, it’s made in the USA. With so many companies moving over seas, it’s nice to find something made here. The air chuck is very well built and lastly, it was on sale for a very affordable price. Upon arrival, I also installed Milton S-684-4 1/4" MNPT Male Tank Valve (B001PLI4BA) so I could keep my locking air chuck on my wireless compressor and quickly connect this this one when needed. I will note that the locking air chuck I have on my more convenient wireless compressor is not removable so thought a quick plug is more of the industry norm, the Male Tank Valve was a better fit for my needs. This Milton Dual Air Chuck Part No: A-S-693 what just the right size to use with the MagBak RimCase fitting as thought the opening in the RimCase was made for it. Pros: - Well built - Got it on sale for a great price - Reputable company and made in the USA Cons: - There really are none. Would I recommend this item to a friend? Yeah. Works great and is just what I needed.

## Questions & Answers

**Q: What is meant by not for use with an inflator gauge?**
A: Ive been using mine with my inflator gauge with no issues...

**Q: This straight foot chuck will not interchange with the milton s-506 angle chuck. what am i missing?**
A: You can’t use part# s-693 with the s-506 inflator . if you are trying use it because of the chuck then you can buy P516 CHUCK  . The NPT  on the s-693 is ¼ NPT and on the s-506 is 1/8-27 .NPT , so the P516 will fit on the s-506 because the NPT are the some 1/8-27 NPT

A: works on my commercial trailer valve stems for inside and outside dual tires.

**Q: What is the overall length, end to end, of this air chuck? Dimensions given seem to be package size.**
A: These are about 7" overall, with the female air chuck installed. Great for truck dually tires & deep rims. They are Milton products best in the industry!
