Shorter scupper valves made to fit the Old Town Topwater 106, 120, 106 PDL, and 120 PDL. The shorter design allows them to fit flush with the cockpit surface of the kayak, eliminating interference with seating, standing, crates, and other cargo.
Medium Size Scupper One-Way Valve, 1 3/8 in. dia. Designed to keep water from entering up from the scupper holes AND will let any water drain out of the cockpit seating area. One size only! See the *OK SIZE CHART WINDOW*to find out which Ocean Kayak models this scupper valve will fit, search for size MEDIUM. (Valves of other size holes are not available at this time.) Can be used to replace valves on the Aquaterra Prism.
The rubber flap from this valve is an exact match to the same rubber flapper valve found in Hydra Adventurer scupper drains. See How To: Hydra Adventurer Scupper Drains. The flapper valves (aka Umbrella Valve) are not sold separately. The rubber Umbrella Valve can be gently removed from the OK valve assembly and fit into the cross hairs of the Hydra Adventurer scupper drains.
The OK Scupper Valves can fit some other brands of sit-on-top kayaks. You will have to measure your scupper hole diameter. The Scupper one-way valve medium is 1 3/8 inches in diameter. 1 inch tall. (07.2000.0782)
