Abstract: The present invention is directed to a system for reducing the noise that enters the vehicle compartment through a hole in a drain plug. In an embodiment, the system includes a drain plug with a washer, a shank with an inlet fluidly coupled to an outlet, a cylindrical wall and a disc configured to occlude the outlet. The assembly may include a seal. When installed, the seal seals the washer to the mounting surface while the disc occludes the outlet so as to reduce the entry of noise through the drain plug while providing a passageway that allows the accumulated water to drain away.

Abstract: The hole plug includes a peripheral planar ledge with a wall formed perpendicular therewith. A gasket seats within the intersection of the planar ledge and the wall. The gasket includes inwardly extending tabs (or “dogs”) which extend into corresponding pockets (or “doghouses”) formed in the wall. This causes the gasket, which is initially provided in a non-tacky state, to be mechanically secured to the hole plug during shipment and assembly prior to installation.

Abstract: A linear bushing attachable to a structural member is formed of a tubular body having a tail part and a lead part forward of said tail part, the tubular body defining a cylindrical wall about a central longitudinal axis and having inner and outer surfaces. First and second sets of resiliently bendable arms extend respectively from the lead part and from the tail part, the arms of each set being spaced apart circumferentially and extending generally forwardly and radially inwardly. The arms of each set have distal ends with inner surfaces which define a bore of first diameter, these arms of each set being deflectable radially outward to define between the inner surfaces of their distal ends a bore of greater diameter than the first diameter. Each of these arms when deflected radially outward applies a resilient opposite radially inward force.
