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.

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:

Great product—terrific price—arrived quickly— etrailer always exceeds my expectations



by:

Well - there’s not much to say about this. It fits as it is suppose to, and it keeps dirt and moisture out of the air fittings for my supplemental braking system when the truck is not connected to the motor home.



by:

Mine delivered were not shaped like the picture. The diameter is the same and does not slim down to shape of democrats fitting.

I am glad that you caught that! The design has changed so that it is straight instead of tapered at the end. We will be updating the picture as soon as we can.



by:

Fits perfectly to cover the tubing on our vehicle brake system. Lost the original. grateful to find a replacement.



by:

As describe.



by:

It’s simple and works. Just be careful not to misplace them!



by:

Everything was as ordered. It arrived when I was told it would be. Several orders from etrailer and never a problem.



by:

Left the caps to the air lines on the front bumper of the toad Jeep. Price is expensive enough to jhopefully jar my memory the next time, but not so bad it breaks the bank. Exactly as described, fast shipping and great customer service will continue to make me a repeat customer. No whining now…



by:

This is the cap that goes on the female air connection when your air force braking system is not connected. It keeps the connection protected and clean.



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:

Some how the first delivery got lost in the mail even though it showed it was delivered. I called to let etrailer know and with out doubting they immediately resent my order which I received. That’s the way you do business.
I been in business as a General Contractor for 47 years and my policy has been, if you 99 things for your client and you don’t do the last one that’s the one they will remember. I have lived by that and it appears that E trailer has the same policy.

Perfect spare in case I lose the origin al



by:

This was a replacement for one that was lost. Have it already on vehicle and fit perfectly. Ordered an extra one for a spare.

caps worked real well. other parts u list I did not buy



by:

Exactly what I needed to keep air connections clean when not in use. As always etrailer had the item in stock and shipped out to me in a very timely manner.



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.

Air line fitting covers are still going strong!



by:

Great products, website is awesome



by:

I’ve still got the original caps. They are in very good condition after 8 years. It’s a good to have extras.



by:

Works great, keep spares on hand.



by:

I made an online order and the product showed up on time! Easy to do business with!



by:

Fits like a glove. Ordered extra just in case. It would be nice if the cap had a retainer string/cord to attach it to the tow vehicle. But for now the cap is great!



by:

Perfect fit



by:

Fits perfectly. I’ll have to say that entailed has those hard to find trailer parts.



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.
