3/16″ × 16′ Stainless-Steel Gravel & Rock Guard

Extend the life of your hard lines with the 4LifetimeLines® 3/16″ × 16′ Stainless-Steel Gravel & Rock Guard. This flexible spring coil slips over standard 3/16″ tubing to deflect rocks, gravel, and brush before they abrade or puncture your lines. Made from marine-grade 316L stainless steel, it resists corrosion and remains pliable in extreme temperatures, making it ideal for off-road rigs, farm equipment, and any vehicle facing harsh terrain.

Built for Impact Resistance

Unlike plastic sleeves that crack or peel, the helical stainless coil absorbs impacts and sheds debris, preventing dents and abrasion along the entire run. Its universal inner diameter fits snugly over brake, fuel, or hydraulic lines—no adapters or special fittings required. The full 16′ length gives you plenty of material to cover long runs or multiple sections, and you can trim it precisely with standard snips.

Long-Term Corrosion Protection

Salt, mud, and moisture are no match for 316L stainless steel. Once installed, this gravel guard will deliver years of rust-free performance, cutting down on seasonal maintenance and costly line replacements. It’s the simplest way to safeguard your hard-line system whether you’re driving through desert washes, rocky trails, or snowy backroads.

Easy Installation

Measure the length of tubing you need to protect and cut the coil guard an inch longer to ensure full coverage. Slide it onto the line before routing, pushing it along until the entire exposed section is covered. For extra retention, secure the ends with zip-ties or mini-hose clamps. Once in place, you can bend and shape your lines as usual, knowing the guard will flex with every turn.
