Abstract
A dual compound bushing includes a tube having a first end, a second end, and an intermediate portion extending therebetween. A first elastomeric member having a first durometer value is arranged on the intermediate portion. A second elastomeric member having a second durometer value that is distinct from the first durometer value is arranged at the first end. A ferrule is mounted to the tube at the first end. The second elastomeric member being arranged between the ferrule and the first elastomeric member.

A dual compound bushing comprising:
- a tube including a first end, a second end, and an intermediate portion extending therebetween;
- a first elastomeric member having a first durometer value arranged on the intermediate portion;
- a second elastomeric member having a second durometer value that is distinct from the first durometer value arranged at the first end;
- and
- a ferrule mounted to the tube at the first end, the second elastomeric member being arranged between the ferrule and the first elastomeric member.
A method of forming a dual compound bushing comprising:
- mounting a first elastomeric member having a first durometer value about an intermediate portion of a tube;
- positioning a second elastomeric member having a second durometer value distinct from the first durometer value at a first end of the tube;
- and
- securing the second elastomeric member to the tube with a ferrule.
