Eheim 16/22mm to Eheim 25/34mm Barb Adapter
This adapter is a reducer. It steps between 16/22mm hose and 25/34mm hose, one end sized for each hose. Push each end on by hand for a snug, push-fit connection. No clamp needed, though you can add one if you want extra hold. See the fitment table below for the exact sizes this part fits. We print in PETG. Aquarium keepers have used it submerged for years. Rinse before use.
