Most Power Bleeders manufactured before May 2008 do not include the threaded fittings required to enable the interchange of adapters.
This kit includes the fittings and simple instructions to enable you to convert your base-model Power Bleeder to accept additional adapters and bleed the brakes of more vehicles. Adapters sold separately.
Note: if your Motive Products Power Bleeder does not have a set of brass fittings midway between the tank and the cap and you are buying any adapter caps you will need to purchase this kit. Motive Products Bleeders Manufactured after May 2008 will not need this kit.
