made to fit all Dri-Slide* 4oz. plastic spout top bottles, including the Bike-Aid, Multi-Purpose, and Weapons Lubricant. Self threads on spout top bottles. Very thin, fragile needle that allows just a drop of Drislide in the smallest places. Great way to lubricate the inside of many lock assemblies, including car locks and door locks, and perfect for lubricating harder to reach areas. Designed to fit into a cable sleeve, with the cable still in it.
