3/8″ × 25′ 316L Stainless-Steel Tubing Coil

This 25-foot coil of 316L marine-grade stainless-steel tubing is engineered for heavy-duty brake, fuel, and hydraulic hard-line applications. With a robust 0.028″ wall thickness that exceeds SAE J527 and FMVSS 106 burst-pressure standards, it delivers race-ready strength and dependable performance under repeated high-pressure stops.

Lifetime Corrosion Protection

Unlike zinc-coated or galvanized steel, the 316L alloy resists road salt, brake-fluid vapors, and coastal humidity without pitting, flaking, or rusting. Install once and enjoy decades of leak-free service—even in salt-belt winters and marine environments.

Precision Fabrication

The consistent wall thickness and polished OD ensure clean, kink-free bends and flawless inverted or double flares on the first pass. Whether you’re using a manual bender or precision tooling, this tubing holds its shape and seals perfectly with DOT-approved fittings. It’s fully compatible with DOT 3, DOT 4, DOT 5.1, and racing fluids without chemical breakdown.

Installation & Usage

Cut the coil to your desired lengths, deburr each end, and position the tube in your flaring tool or tubing bender. The uniform OD guarantees a snug fit in SAE unions, tees, and adapters. For professional results, pair with our Precision Tubing Bender and Universal Hydraulic Flaring Set.

Who It’s For

Professional mechanics, performance enthusiasts, and DIY restorers rely on this 3/8″ stainless-steel tubing coil for custom brake-line runs, big-brake upgrades, and hydraulic systems. Its combination of corrosion immunity, high-pressure strength, and fabrication ease makes it the go-to choice for any hard-line project.
