Today, we're taking a look at a replacement air jumper. Now, this replaces the air jumper for SMI Air Force One supplemental braking system, part number SM99202. This coiled air hose connects your air assembly in the RV to the operating unit on the towed vehicle. It has the quick connect ends that makes the unit easy to attach and detach. These ends are corrosion-resistant when it comes to the finishing, so it's gonna keep the quick connect safe from rust and corrosion. It is a direct replacement part, straight from the manufacturer, and it's blue in color when it comes to the hose, and the length when it's fully stretched out is around 7 feet long.
That's gonna do it for today's look at the replacement air jumper for the SMI Air Force One supplemental braking system, part number SM99202.
The hardest part was figuring out exactly what part I needed for my type of vehicle and motorhome connection. I followed the directions on this website and it worked out perfectly. The hose is great! Just what I needed.
We needed this part to tow our car behind our motorhome. Etrailer said UPS could deliver it in 1 day so I paid extra for UPS and the next day it arrived.
Amy J was so helpful assisting in my product choice. I have ordered from e-trailer before and have always been impressed with their expertise quick response. Thank you, Amy.

I needed this fast as the one I had disconnected and was damaged. It came within 48 hrs but it was the wrong part. The website asked for my vehicle and this is the part it said I needed however it didn't ask if my vehicle was on a Freightliner or a Spartan chassis. There is a difference and the one I got didn't fit. I had no choice as I needed it right away so I swapped the fittings with the damaged one to make it work.
Etrailer is awesome. If you don’t know exactly what part you need, customer service always seems to know what you’re needing. Order lots of trailer parts and they are usually the cheapest and shipping is fast. Quality of parts is always good.
It was a perfect match for my existing Demco airbrake hose and it arrived promptly. Now I have a spare.
We were on the road and somehow lost our jumper air hose. Without it we had no towed brakes. Thanks for helping get the new part to our camp site and get us back on the road.

We have managed to not lose our new hose you only do that once and the hose is working as it should.
E trailer always has the hard to find products. I always look for. Not only that, they spend time with great explanations and videos on how to use some of these products. Each trailer is a great site.
Just arrived so have not used it. It appears to be a direct replacement for my old damaged air hose. Once I get to use it and if it performs as expected i would then give it a 5.
Product arrived on-time as promised and fits perfectly! Thanks for getting me back on the road.
This hose was the exact part that I nee ded.
Perfect replacement for my Demco AFO. Fits correctly, and now I have a spare in case the original fails.
Customer service was outstanding.
Perfect replacement part, great service and reasonable price!
Etrailer was geat!
Item was delivered promptly as advertis ed
My RV mechanic shop couldn’t find a new air jumper. I looked it up on the internet and etrailer was the 1st website to be displayed. I received it in less than a week and it works perfectly.

My RV shop couldnt get the air jumper. I found you guys on the internet and received the hose in 4 days. It still works great after one year.
I had to order twice and return the first shipment but the second order was OK and snaps easily in my Air Force One behind my RV and in the front of my tow.
Perfect replacement part, easy to order and a decent price

This product is still working great. Holding up well with absolutely no issues. I predict many more years of carefree service
The air hose is of the right size and works well.
Just like the one from the kit, I needed to change a fitting but it works fine.
I just returned from a 3100 mile trip where my current air brake hose started leaking as the result of an earlier accident. i must have checked 15 retail shops and RV centers along the way for a replacement product, no one had a separate hose, only the full air force one system. i found your company online and was happy that the product arrived ahead of schedule and works perfectly.

All great!
The snap ring to keep it locked on the male fitting is weak. I have to really work to make sure it locks in place. It has come disconnected a few times.
