Expert Reply:
I measured the Replacement Check Valve for SMI Supplemental Braking Systems # SM99909 for you. The overall diameter at the barbs for each end is 0.42 inches. The more narrow parts at the base have a diameter of 0.37 inches.
The center, widest section is 0.76 inches in diameter. The overall length is 1.66 inches. This valve was designed to work with the Air Force One SM99202 or # SM99243 and Stay-IN-Play Duo # SM99251. So if you have one of these systems this is the correct replacement.
If you have the Roadmaster InvisiBrake, # RM-98700, then you would instead need # RM-452141.
