Brake Pipe Union - a female threaded union nut for the brake hydraulic pipework, with a 7/16"-20 UNF thread sized for 1/4" brake pipe.

It fastens and seals a brake pipe to a hydraulic component or junction within the braking circuit, drawing the pipe's flared end against the mating seat so the connection holds line pressure without leaking.

Frequently asked questions

What is the HU4A brake pipe union used for?

The HU4A is a female brake pipe union nut with a 7/16"-20 UNF thread, sized for 1/4" brake pipe. It draws a pipe's flared end against its mating seat in the braking circuit so the joint holds hydraulic pressure without leaking. Fits Defender and Series 2 and 3.

Is this the male or female brake union?

This is the female union nut, the part with the internal 7/16"-20 UNF thread that receives the male pipe end or fitting. Check whether your circuit needs the female nut or a male union before ordering, as the two aren't interchangeable.

How many brake unions are typically needed for a pipe repair?

Typically you'll need one union per pipe end being made up, so a single replacement run can use two or more. They're usually sold individually, so count the joints on the section of pipe you're renewing before ordering.
