Coated Line #3Str to Str Steel Ends 40in

The Coated Line #3Str to Str Steel Ends 40in brake hose is a purpose-built fluid transfer assembly engineered for high-pressure hydraulic braking systems in automotive and motorsport applications. This 40-inch hose serves as a critical link between master cylinders and brake calipers, where reliable fluid delivery under extreme pressure is non-negotiable. Built by ALLSTAR PERFORMANCE—a trusted name in racing and performance hydraulics—this hose is designed for technicians and enthusiasts who demand consistency and durability in brake system architecture.

Constructed with a 3 AN (3/16-inch) braided stainless steel core and PTFE (Teflon) lining, the Coated Line #3Str to Str Steel Ends 40in eliminates fluid absorption and resists thermal degradation common in inferior hose materials. The PTFE inner layer ensures smooth fluid flow while preventing swelling or chemical breakdown under sustained high temperatures and pressure cycles. Both ends terminate in 3 AN straight female fittings—stainless steel construction—enabling direct port-to-port connections without adapters. The black vinyl external coating protects against abrasion, UV exposure, and accidental contact with engine bay components, extending service life and maintaining professional appearance.

This assembly is ideal for custom brake line fabrication in race cars, off-road vehicles, and street rods where OEM hose lengths or routing configurations prove inadequate. The 40-inch length accommodates mid-size to full-size chassis with flexible run paths. Technicians working on hydraulic brake systems—whether in competition, restoration, or high-performance street builds—will appreciate the stainless steel construction's corrosion resistance and the PTFE lining's compatibility with all DOT-approved brake fluids. Installation requires no special tools beyond a wrench for AN fitting connections; the straight-to-straight configuration simplifies port alignment and reduces leak risk at termination points.
