The Lid Dropper Slide Bumper is made of durable HDPE and is used on all Wild Goose Filling Lid Dropper assemblies.
This part presses on to the sides of the Lid Dropper Slide helps reduce friction between the Lid Dropper Slide and the Lid Dropper Baseplate.
There are two Lid Dropper Slide Bumpers per Lid Dropper Slide.
