Abstract
A method of reducing the force required to insert an elastomeric seal in a cavity of a metallic member includes tumbling the member in a tumbling machine with media to decrease the surface roughness of the member. Preferably, the tumbling step includes decreasing the surface roughness of the metallic member at least a portion of the member defining an entrance to the cavity. The method is particularly useful for reducing the force required to insert fuel injectors having top O-rings into fuel rail cups.
