When you want the strongest 3/16" line you can put on a vehicle -- and a finish that looks the part -- stainless steel is the answer. It's the hardest, most durable brake line material, built for show cars, off-road and marine builds, and anything that lives in salt.
Working with 3/16" stainless
Stainless is stiffer than copper-nickel, so it rewards a quality hydraulic or bench flaring tool for clean, consistent double and bubble flares. It won't rust, resists abrasion, and handles the highest hydraulic pressures. Match the tube nut on your existing line -- 3/16" fits most brake circuits.
Prefer an easier-to-bend option? Compare with 3/16" copper-nickel. Shop all stainless brake line, add fittings and a flaring tool, or browse all brake lines.
