3/16″ × 25′ Stainless-Steel Tubing Coil

This 25-foot coil of 316L marine-grade stainless-steel tubing is engineered for long-term corrosion resistance and precise brake-line fabrication. With a wall thickness of 0.028″, it exceeds SAE J527 and FMVSS 106 burst-pressure specifications for reliable, street-legal performance. Whether you’re restoring a classic car, upgrading to high-performance brakes, or fitting a fleet vehicle in salt-belt territory, this tubing delivers consistent strength and a firm pedal feel under repeated heavy braking.

Superior Corrosion Protection

Unlike zinc-coated or galvanized steel, the 316L alloy resists road salt, winter brine, and coastal humidity without pitting or flaking. You’ll get decades of leak-free service even in the harshest environments, eliminating seasonal brake-line replacements and shop callbacks.

Precision Fabrication

The uniform wall thickness and smooth interior finish make bending and flaring effortless. Softer than steel but stiffer than copper-nickel, this tubing forms inverted and double flares cleanly on the first try, ensuring a perfect seal every time. It’s fully compatible with all DOT 3, DOT 4, DOT 5.1, and racing brake fluids without risk of chemical breakdown.

Installation & Usage

Cut the coil to your desired length, deburr each end, and position the tube in your flaring tool or bender. The consistent outer diameter ensures a snug fit in SAE fittings and adapters, while the precision wall thickness maintains a firm brake pedal response. For best results, pair with our Precision Tubing Bender and Universal Hydraulic Flaring Set.

Who It’s For

Professional shops, performance enthusiasts, and DIY mechanics trust this stainless-steel tubing for applications ranging from big-brake upgrades to custom hard-line routing on off-road rigs. Its combination of race-ready strength, corrosion immunity, and fabrication ease makes it the go-to choice for any brake-line project.
