Video Transcript for Demco SMI Air Force One Braking System Air Valve Cap Review

So it's never a bad idea to pick up a replacement small plug, and a large plug for your tow vehicle and your towed vehicle. This is what's going to ensure the longevity and smooth running of your SMI system. This is going to go over the end of your female and male end, so that you don't have to worry about getting any dirt or debris inside your air hose fitting when you're not using it. We'll put one on our vehicle end too, just to keep the dirt and debris out of that also.My personal opinion, if I had a system just like this, I would want to make sure all of my plugs are all plugged up before I go anywhere after my trip. So that means when I unhook my air hose that stretch from my towed vehicle to my tow vehicle, I'm going to pick up a couple of these extra plugs and put them over top of the fittings on my hose too, just to make sure everything in that hose stays nice and clean.Well guys, with all that being said, that's going to do it for our review and replacement of our large and small rubber caps.

I think this is way too much to charge for these simple dust covers. Should be at least 6 pieces for this price.
by:
Perfect fit. A little pricey, but works well
by:
I bought some spare large and small air fitting covers used on our SMI Air Force One supplemental braking system. These small plastic covers can split after some use--as have the ones in use on my system. Not much more to say. They keep the dirt out of the lines. I always like to have a few spares.
Etrailer always gives good service. I usually look to them first for RV related parts.

Perfect replacement caps! If you're like me and put these things in your pocket when hooking and unhooking, eventually one will go missing. I now have spares for the next time!
Great service and fast shipping!

Perfect. Thanks!

Got them very rapidly
by:
I purchased spare Vinyl Caps for my Demco SBS Air Force one Breaking system for good measure. The caps can get lost and the idea of dirt and water getting into your connection points when your not connect isn't a good thing. I placed the order with etrailer and before I finished the process, etrailer had my parts sent to me. both the caps I ordered and etrailer are awesome. I would highly recommend buying from etrailer for your RVing needs.
by:
Hard to find caps over the ports on the vehicle, related to the Air Force One supplemental braking system. Caps fit properly and are still in use 1 year later. These ports can be stolen by insects, specifically wasps, looking for a hiding place when RV is in storage, so the caps are necessary to keep out pests and dirt that may foul the air line. Keeping them covered is the best choice on both the motorhome and the tow vehicle.
by:
This hitch is amazing!!! Be prepared though it is very heavy! I love how easy it is to adjust to different heights and ball sizes with the 2 common sizes provided. The scale on the back can be helpful to let you know if you have the proper trailer weight. The more you use it the more you will like it!
by:
ETrailer provided me with excellent support. The parts were back ordered from the manufacturer. eTrailer kept me informed on the delivery status. Thanks.

Excellent. After hearing stories from others who bought less expensive brake controllers Im positive I made the right choice.

by:
I purchased these extra air fitting caps for my Air Force One supplemental braking system because only one of each came with the system, they are essential for keeping the air lines clean, and it woud be easy to lose or misplace them. I received exactly what I ordered, and the price and delivery time were good.
by:
Etrailer is the place we to go to for just about any part. Good prices and quick service. Thx!

Easy to hook up

by:
I bought a number of these dust caps for the quick connect fitting of our auxiliary brake system. Because the plastic caps bend when being put on or pulled off, the ends of the caps can split.
The replacement caps work fine and my current supply should be good for several more years.
by:
Small but necessary part for brake system to keep air valve clean. Thanks etrailer!
