Needle routing valve provides precise variable control of air or water volume on a dental delivery unit. Product Details: Use With: 1/8" or 1/4" tubing. Includes: large and small barbs, large and small tubing clamps, and gaskets included. NOTE: For a replacement knob, see #05-19. Instructions (PDF): Shut off your delivery unit by depressing the buttons on the air/water syringe. Cut the tubing as close to the old toggle with a wire cutter and remove the toggle. Make sure to note which tubing connects to the inlet and outlet. Install the appropriate sized barbs with washers and tighten securely with a 1/4" open ended wrench. Apply liquid soap to the tubing or dip the ends in hot water. Slip the sleeve clamps over the tubing (approximately 3/8" from the end), which ensures the interior bevel of the sleeve clamp faces the barb. Slip tubing over barbs and lock tubing by using a pliers or sleeve tool to slide the sleeve clamps over tubing and barb. Mount to the delivery unit using provided nut. Finally, turn the unit on in order to test for leaks and proper function.
