Upgrade your vehicle’s hardline plumbing with the Earl’s 3/16 in. Easy-Form Copper-Nickel Hardline Tubing Kit, engineered for strength, corrosion resistance, and simplified installation. Manufactured from a premium copper-nickel alloy containing approximately 90% copper and 10% nickel, this tubing delivers steel-like durability while remaining far easier to bend and flare. Designed for precision fitment, it can be formed by hand without a tubing bender, making it ideal for professional shops and DIY builders alike.
This DOT-approved hardline tubing has been trusted in OEM applications since the 1970s and is suitable for brake lines, fuel lines, transmission cooler lines, and other automotive fluid systems. Unlike standard copper tubing, Easy-Form resists rust and corrosion while supporting a high 4,200 PSI working pressure. This kit includes multiple tube nuts in common thread sizes, providing added convenience and compatibility for complete hardline installations.
Features:
Easy-Form copper-nickel alloy for strength and effortless forming
3/16 in. diameter tubing for automotive hardline applications
DOT approved for hydraulic brake system use
Excellent corrosion resistance for long service life
Includes tube nuts in multiple thread sizes for versatile fitment
25 ft. length ideal for complete vehicle plumbing projects
