Hard Lines & Fittings

Hard lines and fittings are used in performance automotive plumbing systems where strength, rigidity and precise routing are required. Hardline plumbing offers a clean, professional solution for applications where flexible hose is not ideal, particularly in high-temperature or high-vibration environments.

Hard lines are commonly used in fuel, brake, oil and coolant systems across performance street cars, track vehicles and motorsport builds. When paired with the correct fittings, hardline systems provide consistent flow, excellent durability and long-term reliability while maintaining a tidy and secure installation.

This collection includes hardline tubing and compatible fittings suitable for a wide range of automotive fluid systems. Whether you’re fabricating custom lines, replacing factory hardlines or building a complete performance plumbing setup, hard lines and fittings allow for accurate routing and dependable system performance.
