3/16 inch x 25 ft 316L Marine Grade Stainless Steel Brake Line Tubing Coil - Universal - 4LIFETIMELINES

3/16 inch outside diameter 316L marine-grade stainless steel brake line tubing on a 25 foot coil. Universal fitment for custom brake line fabrication on any domestic, European, Japanese, or British vehicle. 316L stainless with added molybdenum resists rust and corrosion far better than standard steel or coated tubing - the right choice for coastal areas, restoration projects, or anywhere road salt is a factor.

Specifications

• Outside diameter: 3/16 inch (4.76 mm) - the standard automotive brake line size
• Length: 25 feet (7.6 meters)
• Material: 316L stainless steel with molybdenum
• Manufacturing: Seamlessly drawn, kink-resistant, holds shape during bending
• Compliance: Meets SAE hydraulic brake line specifications
• Fittings: Not included - order 3/16 inch inverted flare fittings and tube nuts separately

Common Uses

• Full brake line replacement on classic and restoration vehicles
• Rusted hard-line replacement on daily drivers in rust-belt states
• Custom fabrication for hot rods, off-road builds, and race vehicles
• Marine and industrial hydraulic applications where corrosion is a factor

Fabrication Notes

• Tube bender required - stainless is harder than plain steel; use a purpose-made tubing bender to prevent kinking
• Double-flare or ISO/bubble-flare both possible with the correct tool - match your vehicle's existing fitting style
• Deburr and clean every cut end before flaring - metal shavings in the brake system cause seal damage
• Match with SAE fittings - inverted-flare tube nuts, banjo bolts, or bulkhead unions depending on the application

Why 316L Over Standard Steel Line

• Corrosion resistance - 316L is the marine-grade stainless alloy used on boats and offshore hardware; road salt does not attack it
• Longer service life - once installed, 316L brake line effectively lasts the life of the vehicle
• Pressure capacity exceeds SAE minimum by a wide margin, appropriate for high-performance and heavy-duty use
