Use the Fly High 3/4" Hose / Sac Thread Adapter for permanent integrated ballast connections. Securely connects 3/4" hose via a barbed fitting directly to the threaded ports built into all Fly High Pro X Series ballast bags.

If you plan on removing your bags regularly for cleaning and storage, or if you need a 90 degree fitting for limited clearance, you'll probably want to consider the Flow-Rite 3/4" Quick Connect fitting system instead, but otherwise this less expensive barbed fitting will work just fine if you don't remove your bags from the boat regularly.
