Frequently asked questions

What is the HU1 brake union and what does it do?
The HU1 is a male brake pipe union with a 3/8-24 UNF thread, machined from brass. It connects a 3/16 inch hydraulic brake pipe into the brake circuit, clamping the flared pipe end against its seat to form a pressure-tight joint. The imperial thread suits early Land Rover brake systems.
How many brake unions do I need?
Brake pipe unions are needed at each joint in the system, so quantity depends on how many pipe ends you're making up. The HU1 is supplied individually. When remaking brake lines it's common to fit new unions throughout rather than reuse old fittings.
What's the difference between the male and female 3/8-24 UNF brake unions?
The male union has an external 3/8-24 UNF thread that screws into a female port, while the female version has an internal thread. Both are imperial fittings for 3/16 inch pipe. Match the gender and thread to the component you're connecting, and don't confuse them with metric M10 unions.
Which Land Rovers use this imperial brake union?
This 3/8-24 UNF imperial union suits Series II and III and early Defender models built with imperial brake fittings. Land Rover later moved to metric brake threads, so confirm your vehicle uses imperial unions before ordering.
