Abstract
A brake pipe fitting tool includes a first hydraulic pipe wrench, a second hydraulic pipe wrench, a connecting portion and a handle portion. The first hydraulic pipe wrench has a first jaw defining a first hydraulic pipe insertion opening. The second hydraulic pipe wrench has a second jaw defining a second hydraulic pipe insertion opening. The connecting portion connects the first hydraulic pipe wrench to the second hydraulic pipe wrench such that the first hydraulic pipe wrench and the second hydraulic pipe wrench are fixedly and rigidly connected to one another and spaced apart from one another by a predetermined distance. The first hydraulic pipe insertion opening and the second hydraulic pipe insertion opening are parallel to one another and aligned with one another. The handle portion is rigidly fixed to one of the first hydraulic pipe wrench, the second hydraulic pipe wrench or the connecting portion.
