All Brass

The female (3/8-24 I) to male (9/16-20 I) brake line adapter comes in packs of 10. For unsurpassed brake line fluid sealing, these brake line adapters are made from brass. They are then plated for corrosion resistance. These adapters are versatile because they can be used with other materials like steel and PVC tubing.
