Unions are used to join two brakes, fuel, or transmission lines together. This may be needed, for example, in long runs from the dual master cylinder to the rear axle. Match the thread and flare type to the lines being connected. It is important that both flare type and thread match for a leak-proof connection. Use for joining 3/16" Domestic brake lines.
