About This Product
These MCS brake line adapter fittings are essential for plumbing custom or replacement hydraulic systems on Harley-Davidson models. Constructed from durable steel, each fitting features a 90-degree bend with a 1/8 inch NPT male thread on one end and a 3/8-24 inverted flare on the other. These components are often used to connect brake lines to calipers or master cylinders, ensuring a secure and leak-free connection. They serve as a direct replacement for OEM 43307-78 and are sold in packs of 5, making them a practical choice for workshop inventory or complete bike builds requiring multiple junction points.
Manufacturer part number: 507175.
