3/16in Brake Line 40in Stainless Steel

The 3/16in brake line 40in stainless steel from ALLSTAR PERFORMANCE is a precision hard line engineered for custom brake system builds and modifications. Whether you're fabricating a standalone brake circuit, extending existing lines in a custom chassis, or upgrading a street rod or race vehicle, this stainless steel line delivers the durability and corrosion resistance required for long-term reliability. Pre-flared with 3/8-24 flare nuts on both ends, it eliminates the need for on-site flaring and ensures leak-free connections in hydraulic brake systems.

Constructed from seamless stainless steel tubing with a nominal 3/16-inch inner diameter, this brake line resists rust and corrosion far better than mild steel alternatives, critical in wet climates or undercarriage environments where salt exposure is a concern. The 40-inch length provides flexibility for custom routing through engine bays, chassis tunnels, and between frame rails without excessive bending or compression points that restrict fluid flow. The pre-installed 3/8-24 flare nuts—meeting industry standard SAE specifications—ensure compatibility with common brake components and master cylinders, while the stainless construction maintains its finish and structural integrity through repeated thermal cycling and high-pressure cycling typical of performance braking.

Mechanics and fabricators building disc brake conversions, dual-circuit systems, or custom hot rod brakes benefit most from this line's ready-to-install design and premium material choice. The 40-inch length suits most frame-mounted to caliper runs on mid-size and full-size vehicles, though custom applications may require cutting or extending with additional fittings. Installation requires standard brake fittings and a clean, debris-free assembly process to maintain system integrity—always flush lines before final connection and bleed the system thoroughly to remove air.
