The ICON Vehicle Dynamics Economy Needle Charging Tool is an essential service tool for nitrogen charging ICON internal reservoir shock absorbers equipped with self-sealing charge ports. Designed for occasional service use, the tool utilizes a replaceable 20 GA x 1-inch hypodermic needle that pierces the charge port plug to inject nitrogen, with the self-sealing plug automatically resealing upon needle removal. Precision CNC machined brass fittings provide durability and a reliable connection, while standard 1/4-inch NPT threads allow easy attachment to a nitrogen supply hose and regulator. Economically priced and simple to use, the ICON Economy Needle Charging Tool offers a convenient and dependable solution for properly servicing ICON internal reservoir shocks.
