ABSTRACT:
An oil drainage coupler that enables a single fitting to be coupled to associated oil drainage plugs of various sizes thereby enabling oil to be quickly drained from all makes and models of vehicles. This coupler produces a vacuum-tight seal that enables a vacuum pump to be used to enhance the rate at which oil is drained. The two halves of this coupler can be coupled by a rotation of one half into the other by an angle less than 90.degree., thereby making this a quick coupler that can be coupled by a single quick motion of vehicle service personnel.
