ABSTRACT:
In combination with a dual elbow swivel joint having a female elbow member rotationally coupled to a male elbow member, the invention comprises an orientation device having an angle marker located on one elbow member and an indicator mark located on the other elbow member. The angle marker contains a number of angle markings located at predetermined angles measured from the central axis of the elbow member. The indicator mark is placed on the other elbow member in a location such that, when aligned with an angle marking, the elbow members are in a predetermined angular orientation relative to each other. The angle markings on the angle marker each have a length which is related to the amount of wear that has been found to occur in the dual elbow swivel joint when the female and male members are oriented at that particular angle. Thus, the orientation device enables an operator to orient the female and male elbow members at an angle at which the dual elbow swivel joint will experience the least amount of wear.
