Brake Pipe Union is a male threaded fitting used in the brake hydraulic pipework. It belongs to the brake pipe and fitting group.

The union nut threads into a female port - at a flexible hose end, wheel cylinder or junction block - and clamps the flared end of the pipe to form a pressure-tight seal. This is the male metric type with an M12 x 1mm thread, sized for 3/16in brake pipe.

Frequently asked questions

What is the HU9 brake pipe union used for?

The HU9 brake pipe union is a male threaded fitting used in the brake hydraulic pipework. The union nut threads into a female port at a flexible hose end, wheel cylinder or junction block and clamps the flared pipe end to form a pressure-tight seal. It's the male metric type.

What thread and pipe size is the HU9 union?

The HU9 is the male metric union with an M12 x 1mm thread, sized for 3/16in brake pipe. Check your port is female and metric before ordering, since imperial-threaded unions won't seal correctly. Matching the thread exactly is critical on a brake line.

Which Land Rovers does the HU9 brake union fit?

The HU9 brake pipe union suits the Land Rover Defender up to 2016, Discovery 1 and Range Rover Classic brake systems. It's a generic M12 x 1mm metric union for 3/16in pipe rather than a model-specific part, so it fits any matching female metric port on these models.

Can a brake pipe union be reused?

Replace the HU9 union rather than reusing it once a flared joint has been disturbed, since a reused seal can leak under hydraulic brake pressure. Fit a new union whenever you make up a fresh pipe flare, torque to the workshop manual specification and check for leaks before driving.
