Main Features
316L Marine-Grade Stainless Steel
The 316L stainless construction offers strong resistance to rust, moisture, road salt, and corrosion. This makes it especially useful for vehicles exposed to harsh weather or corrosive environments.
25-Foot Brake Line Coil
The generous 25-foot length provides enough material for fabricating multiple replacement sections or completing extensive brake-line repairs. The tubing can be cut to the required length for individual applications.
High Pressure Capability
With a stated 15,310 PSI burst-pressure rating, the tubing is designed for demanding automotive brake-system applications. Its 0.028-inch wall thickness provides durability while remaining workable with appropriate brake-line tools.
16 SAE Fittings
The kit includes a selection of SAE fittings covering several common thread configurations, including 7/16-24, 3/8-24, 9/16-18, 1/2-20, and metric M10/M12 options. This gives the kit broader application coverage, although exact vehicle compatibility should always be verified.
