Frequently asked questions

What is the HU1A brake union and what does it do?

The HU1A is a female brake pipe union with a 3/8-24 UNF thread, machined from brass. It threads onto a male union body or port and clamps a 3/16 inch flared brake pipe 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 pipe joint, so quantity depends on how many ends you're making up. The HU1A is supplied individually. When remaking brake lines it's common practice to fit new unions throughout rather than reuse old fittings.

What's the difference between the female and male 3/8-24 UNF brake unions?

The female union has an internal 3/8-24 UNF thread and screws onto a male union body, while the male version has an external thread. Both are imperial fittings for 3/16 inch pipe. Match the gender to the part you're joining, and don't mix them with metric M10 unions.

Which Land Rovers use this imperial female brake union?

This 3/8-24 UNF imperial female union suits Series I, Series II and III, and very early Defender models built with imperial brake fittings. Later vehicles use metric brake threads, so confirm your vehicle has imperial unions before ordering.
