Pyranha Drain Bung Kit with Base. This version comes with a base so you can add it to kayaks that don't come with a drain bung. May, or may not come with mounting screws. Sealant is not included. Can be used as a replacement drain plug... or... a base for Pyranha kayaks. It is worth having a spare in your repair kit (especially if you're on a multi-day trip). Pyranha drain bungs feature an integral cord and block to prevent loss. The low profile tab won't get snapped off. Unique Threads. Fits all Pyranha kayaks. May fit Venture or P&H kayaks too.
