The AprilAire 4335 Feed Tube with Sleeve is the water feed tube inside the humidifier, which connects the solenoid valve and then to the water distribution tray at the top of the unit.
The feed tube should be securely attached to the solenoid using a compression sleeve and nut, routed through the humidifier in a manner that allows free flow of water and then inserted into the feed tray far enough to be stopped by the feed tray’s limiting element. Features 1/4-inch Outer Diameter and 3/16-inch Inner Diameter.
