5/16″ × 25′ 316L Stainless-Steel Tubing Coil

This 25-foot coil of 316L marine-grade stainless-steel tubing combines race-ready strength with lifetime corrosion resistance. With a 0.028″ wall thickness surpassing SAE J527 and FMVSS 106 burst-pressure requirements, it’s engineered for heavy-duty brake, fuel, and hydraulic applications—from big-brake upgrades to custom hard-line plumbing on off-road rigs.

Lifetime Corrosion Resistance

Unlike coated or galvanized steel, 316L stainless-steel withstands road salt, brake-fluid vapors, and coastal humidity without pitting or flaking. Install once and drive worry-free for years—no seasonal replacements or rust-related failures.

Precision Fabrication

The uniform wall and polished outside diameter make bending and flaring effortless. This tubing holds its shape under tight bends and produces flawless inverted or double flares on the first pass, whether you’re using a manual bender or precision tooling. Fully compatible with DOT 3, 4, 5.1, and racing fluids, it resists chemical breakdown for consistent performance.

Installation & Usage

Cut the coil to your desired lengths, deburr each end, and position the tube in your flaring tool or bender. Its consistent outside diameter ensures a snug seal in SAE unions, tees, and adapters. For professional-quality results, pair it with our Precision Tubing Bender and Universal Hydraulic Flaring Set.

Who It’s For

Professional shops, performance enthusiasts, and DIY mechanics rely on this 5/16″ tubing coil for robust brake-line runs, transmission-cooling lines, and hydraulic systems. Its combination of high-pressure strength, fabrication ease, and corrosion immunity makes it the go-to choice for any hard-line project.
