Brake pipe pre gmc227 master cyl to pdwa valve 10mm union

Copper Nickel easy bend brake pipe 9″ long with metric male unions both ends. Pipe from the master cylinder when sleeve nut connector for metric type male unions is fitted. On Pre Servo cars before 1988 to allow engine subframe assembly to be installed on the assembly line and then connected to PDWA valve and brake lines fitted already on shell. From 1988 when the servo was fitted they used a pipe from the master with a large female end to join the pipes but we suggest you replace with a single pipe 13″ or 15″ long.
