Aquascape91075 Pump Discharge Fitting Kit for AquaForce 1000 2700 5200 and 4000-8000 GPH Pump

There is a new design to the ball joint. Instead of snapping together, there is now a threaded joint with a collar nut. Much better closure. The old joint would come apart when servicing the pump and I would have to realign the two halves and try to snap them together. Not easy when coated with a thin layer of algae. I'm buying a second one.
