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.

It's the fuel line you are looking for.
sturdy well made line, the coating is nice and easy to bend into shape. Tight corners may kink but that's to be expected.

Working well for me, would purchase the same again
Seems to be working great. The only reason I’m not giving 5 stars is that I really don’t know how to compare it to similar products. This is the first time I’ve worked with steel brake line. In my case, I’m actually using it for fuel line on a tractor, using compression fittings. I’ve been cutting it with a pipe cutter - same type used on copper plumbing pipe - and that works good... leaves a nice square cut, although it’s always a good idea to deburr the ID and OD of the cut before fitting it up. The fittings go on fine - there doesn’t seem to be any problem with fit due to the PVF coating. The coating stays on where I’ve bent the tubing. Hopefully this will keep rust away and this fuel line will last the remaining life of the tractor.
