3/16″ × 12″ Straight Stainless-Steel Brake Line

Elevate your braking reliability with the 4LifetimeLines® 3/16″ × 12″ Straight Stainless-Steel Brake Line. Crafted from marine-grade 316L tubing, this 12-inch hard line resists rust, brake-fluid vapors, and harsh road chemicals, delivering years of leak-free service.

Each tube ships pre-cut and fitted with industry-standard SAE nuts and caps, so you can deburr the end, flare it to DOT specifications, and thread on the fitting for a secure, leak-proof connection. Its straight-through design makes precise routing simple—whether you’re replacing an OEM section in a tight engine bay or fabricating a custom brake-line run on a restoration project.

Fully compliant with DOT FMVSS 106 burst-pressure requirements, this stainless-steel line installs in minutes and stands up to salt-belt winters, coastal humidity, and track-day heat alike. Add the 3/16″ × 12″ Stainless-Steel Brake Line to your cart now and stop worrying about rust-edged failures—drive with confidence, mile after mile.
