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.

You mentioned that it did not fit and I wanted to ask if you were using it on your Quick-Disconnect air valve on your Air Force One supplemental braking system? Do you know the model number of the braking system?

Hi Jenny, yes I’m using a quick disconnect that was on the coach when I bought it. I use a M&G braking system, similar to the AF1. The quick connect air hose fitting I use came with the M&G brake I had installed on my Jeep. The vinyl cap I purchased was to small to go over the female quick connect fitting on the back of the coach...
