1/4″ × 25′ Stainless-Steel Coil & 16′ Gravel Guard Kit

Protect your brake, fuel, or hydraulic hard lines from both corrosion and debris with the 4LifetimeLines® 1/4″ × 25′ Stainless-Steel Coil & 16′ Gravel Guard Kit. The marine-grade 316L tubing delivers race-ready strength and rust-proof durability, while the matching 16′ stainless-steel spring guard deflects rocks, gravel, and brush before they can damage your lines.

What’s Included

25′ of 1/4″ × 0.028″ 316L Stainless-Steel Tubing for custom hard-line runs

16′ of 3/16″–5/16″ Universal Spring Gravel Guard to shield your lines from impacts

SAE Nuts & Caps for each cut end (flare tools sold separately)

Corrosion-Resistant Mounting Clips to secure both tubing and guard

Why Choose This Kit

Combining corrosion resistance with physical protection, this kit eliminates two common failure modes in one package. The stainless tubing resists salt, brake-fluid vapors, and humidity, while the spring guard absorbs and sheds debris without trapping mud or moisture. You’ll save time sourcing separate sleeves and sleeves, and you’ll install with confidence knowing your hard lines are covered inside and out.

Installation & Usage

Cut & Deburr: Trim tubing and guard to length—add an extra inch on the guard for full coverage.

Flare Ends: Form inverted or double flares on your tubing using a flaring tool, then thread on SAE nuts.

Assemble & Secure: Slide the gravel guard over exposed sections, push into place, and fasten both tubing and guard with the included clips.

Bleed & Test: Bleed your brake or hydraulic system for a firm pedal and inspect the guard for proper coverage.


Ready to lock out rust and rock strike in one kit? Add the 1/4″ × 25′ Stainless-Steel Coil & 16′ Gravel Guard Kit to your cart today and drive with total line protection.

Which brake line material is right for you?

Every 4LifetimeLines tubing material is built to last. The difference comes down to corrosion resistance, how easily it bends, and price. Here's how they stack up.
