Abstract
An apparatus, system, and method is provided for preventing the communication of contaminants between connected hollow interiors of tubes of a frame, such as a bicycle frame, for example. A hollow insert may be positioned inside a first tube of a frame such that seals on bottom and top portions of the insert are radially sealed against an interior surface of the first tube on either side of an open intersection between the first tube and other tubes of the frame, so that the interior of the first tube is not open to the interiors of the other tubes of the frame. Contaminants that then enter the first tube, such as through the headset of a bicycle head tube, for example, pass through the interior of the insert and out the bottom of the first tube, instead of passing into the interior of the frame.
