Michael: Hi there. I'm Michael with Etrailer.com. Today, we're going to take a quick look at the Demco replacement female quick disconnect fitting. This is going to replace the female quick disconnect fitting for your Demco Air Force One supplemental braking system.There's really not a whole lot to say about this. This is a direct replacement from Demco. So you can rest assure that it's going to work for your application just like the original did.
So if your original has become damaged or you're just needing to replace it for whatever reason, this is going to be the piece for you. It's going to thread on just like the original and provide that connection point for your airline to connect to your RV so that you can get that air pressure back to your vehicle, to apply the brakes when the RV's brakes are applied.So like I said, this is a Demco product, so you can trust it's going to work. You're not going to have to worry about compatibility issues or anything like that. So if you are needing a replacement female fitting, this is going to be the piece for you. That's going to complete our look for today.
Again, I'm Michael with Etrailer.com. Thanks for watching.
Part was exactly what I needed. Fast shipping and customer service. I always go to etrailer.com.
They work very easily. They work well when they’re on they seal off water getting into the Airlines. I’ve been very pleased with them.
The people at etrailer are great to work with.
Grossly overpriced and shipping was $[XX]. Shipping took 10 days.
etrailer service was great and product quality excellent.
Worth carrying a spare. Had one seize up on the road.
Customer service was excellent! Parts arrived on time as promised and worked perfectly after installation. Every time that I have worked with eTrailer I have been satisfied.
Great Company to work with and order from.
Good replacement!
You shipped it late which created a problem for me!
Excellent service.
The Air Force One parts arrived when scheduled & worked perfectly.
Thought I was buying the female end to repair an air hose. My mistake. Still need the piece that connects this piece to the hose.

Art you were on the right track. This is just one piece of the female quick disconnect. You need part # SM99613.
My purchase was a replacement quick disconnect for a Demco Air Force One flat Tow brake hose. I had reviewed the etrailer website previously lusting over the cargo bay slides... Most other sites only had the entire hose with connectors which was way overkill and expensive for my issue.
Normally I do not review products but appreciate the attention and follow-up of my order. I will deal with etrailer again -- maybe for one of those cargo slides!
Perfect fit? Timely delivery! THANK YO U!

Glad the fitting worked for ya! Are you a full-time RVer?
Our air connector got damaged (actually 2 of them). This part fit perfectly, arrived quickly and is much less expensive than purchasing the whole cord. Thank you!
Needs to have a threades insert when being used as a plug to keep water out when needed
Very timely delivery.
Much thanks
This part was as described. I used to to replace an end in the air hose connected my motorhome to my Jeep for the Airfirce one
Unit.
Timely shipping - fair price - exactly what I needed.
I installed Air Force One in my Wrangler and found the directions and product outstanding.
Great customer service from Virginia who helped me get the correct parts. Quick delivery
As advertised, did take longer than I expected, but not a big issue.
Exactly what I needed.
This part was delivered early and the part fit perfectly! Thank you Josh!!

Still working perfectly. Would buy again in a heart beat! Need to lub it occasionally but that is just regular maintenance.
Item arrived on time and was the exact fit I needed for my Demco air hose. The air hose between my RV and Jeep accidentally dropped on the payment for a couple of miles which destroyed the female quick disconnect fitting. This was an exact replacement.
