3/16" x 25' Stainless Steel Brake Line Kit – Marine-Grade Tubing + Fittings

Upgrade your braking system with the 4Lifetime 3/16" x 25' Stainless Steel Brake Line Kit, built for unmatched durability, precision, and corrosion resistance. Whether you're replacing old brake lines or completing a custom build, this marine-grade stainless steel kit delivers long-lasting performance and pro-level results.

Marine-Grade 316L Stainless Steel
Crafted from 316L stainless steel, the tubing is engineered to resist rust, corrosion, and extreme weather. The 0.028" wall thickness offers superior puncture resistance and supports high-pressure applications—ideal for daily drivers, off-road builds, or classic restorations.

DOT-Fluid Compatible & Leak-Free Performance
Fully compatible with all DOT-approved brake fluids, this tubing ensures safe and secure operation under real-world driving conditions. Paired with 16 precision-machined SAE and metric fittings, the result is a tight, leak-free seal every time.

Flexible and DIY-Friendly
Despite its strength, this stainless steel brake line is easy to bend and flare—allowing you to route lines through tight spaces and create clean inverted flares with standard tools.

    Does not flare nicely for 37 degree

    Nice looking line. But I have to give a 2 star since this line splits when doing 37 degree single flare

    Be prepared and have the proper tools

    There is maybe enough line to last you two life times but probably not enough fittings to last you two life times because I had just enough fittings but more than enough line I like working with this line stainless if you have a nice tubing bender you can make it look like a professional job
