Hello, everybody. This is Jeff at etrailer.com. Today, we're gonna take a look at this replacement vacuum check valve for the Demco SBS Supplemental Braking Systems. This is for a quantity of one valve. Now, this part here replaces a vacuum check valve that came on your Demco SBS Supplemental Braking Systems. This is designed to work with the Air Force One system, part number SM99202 or part number SM99243, and also works on the Stay-IN-Play DUO, which is SM99251.
All three of those systems we do sell separately our website. Now, those systems use two check valves in the vacuum lines. One check valve will install between your brake booster and the tow car's engine, and the other one installs between the operating unit and the vacuum line. Now, these are required on all tow cars that don't have a diesel engine, and this part includes one replacement check valve. But that should do it for the review on the replacement vacuum check valve for the Demco SBS Supplemental Braking Systems.

Replaces the check valve that came with your Demco SBS Air Force One (SM99202 or SM99243) or Stay-IN-Play Duo supplemental braking system (SM99251).I ordered two one way check valves for an aux brake system. It was a good thing they arrived undamaged. They were not packaged individually and thrown into bag that could have been easily crushed with minimal weight. I am not happy about the length of time it took to receive the merchandise and how it was packed!
Needed a check valve to install a braking device on Jeep when towing behind a Class C. Finding the part on the website was a bit challenging but, they had it. Ordering was simple and straightforward.
First class service and very pleasant staff. I was advised of how things were progressing throughout the process right up to and including final delivery. Thank you very much.
Check valve was delivered promptly and fixed the problem I had with the old one.
Exactly what I needed. Bought a used Invisi-Brake and needed a 3/8 check valve for the master cylinder. This part is perfect. Fast shipping and a great price!!
Worked perfectly in my application.
