5/16" PVF-Coated Steel Tubing Coil

The 4LifetimeLines® 25′ × 5/16″ PVF-Coated Steel Tubing Coil delivers factory-grade SAE J527 strength wrapped in a polyvinyl-fluoride barrier that seals out salt, moisture, and chemicals. Ideal for brake, fuel, or transmission hard-line runs, this universal-size coil offers corrosion protection up to 30× better than bare steel—without the premium cost of stainless tubing.

Key Benefits

Advanced Corrosion Defense: The PVF coating blocks road salt, winter brine, and grime to prevent pitting and rust over decades.

OEM-Level Rigidity: 5/16″ SAE J527 tubing maintains a firm, responsive pedal and leak-free performance under high pressure.

Hand-Bend Versatility: The durable coating flexes smoothly around tight bends without cracking or flaking—no special tooling required.

Cost-Effective Durability: Enjoy near-stainless longevity at a fraction of the price, perfect for fleet maintenance, shop inventory, or DIY projects.

Safety-Certified: Exceeds DOT and FMVSS 106 burst-pressure standards for street-legal, high-pressure applications.

Installation & Usage

Measure & Cut: Determine the exact length for your brake, fuel, or transmission run and trim the coil squarely.

Deburr: Remove any sharp edges from the cut end with a tubing reamer.

Route & Shape: Hand-bend the tubing through chassis brackets or hard-to-reach areas, preserving the PVF coating.

Flare & Connect: Create inverted or double flares using your flaring tool, then install SAE flange-nut fittings and torque to spec.

Secure & Inspect: Fasten lines with mounting clips, pressure-bleed or test the system, and verify there are no leaks.
