The hose fits on our Titan pump, Ezee pump and HP pump. It has a Halkey Roberts adapter on one end which connects to the board valve. The other end connects to the pump handle but doesn't screw all the way on to create a tight seal. 

If you're having trouble connecting your hose to the board, push it in and turn right with some force, it can require quite a bit more than you think! If this still doesn't work, look in the end of the hose which attaches to the board to see if there is a grey plastic bar across the middle inside of the hose, if there is, this needs to be knocked out with a tool.
