Eheim 12/16mm to 1/2 Inch Vinyl Barb Adapter, 45 Degree
This adapter connects 12/16mm hose (Eheim Classic 150/250/350/600, JBL InSet) to 1/2 inch clear vinyl tubing. 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. It has a 45 degree bend built in, for tight spots where a straight adapter cannot clear a wall, a stand shelf, or a corner behind the tank. 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.
