The 3/8 x 24NF male end mates with the 1/2 x 20NF female end, making it a practical solution for brake system repairs and modifications where thread sizes do not match directly.

Manufactured by Brakequip, this adaptor is suited for automotive and light commercial brake line applications where thread conversion is required without compromising connection integrity.

Will this adapter work to connect brake lines with different thread sizes on my old truck?

This Brakequip thread adaptor is indeed designed to provide a reliable connection specifically when you're dealing with brake lines that have mismatched thread standards, like converting from 3/8 x 24NF to 1/2 x 20NF.
