Compatible with ballast bags using 1" NPT ports. Designed to be used on Straight Line Sumo Max, Sumo, and Big Bag ballast bags. This cap is a direct replacement in case you lose the fittings that came with the bag. Don't let a dropped fitting ruin your day, we suggest having a back up (or two) on the boat so you can stay on the water.

NOTE: Includes 2 plugs.
