Coated Braided Line 18in #4Hose -4Str/ 1/8in

The ALLSTAR PERFORMANCE Coated Braided Line 18-inch #4 Hose with 4 AN to 1/8 inch NPT Male connection is a precision hydraulic brake hose engineered for high-pressure fluid transfer in performance applications. This 18-inch brake hose assembly delivers reliable fluid delivery with a PTFE-lined interior and stainless steel braided construction protected by black vinyl coating, making it suitable for custom hydraulic systems, street rods, race vehicles, and motorsports builds where pressure integrity and corrosion resistance are non-negotiable.

The 4 AN (AN4) female-to-1/8 inch NPT male configuration provides a versatile connection interface for brake master cylinders and caliper systems. The PTFE (polytetrafluoroethylene) lined bore resists fluid degradation and minimizes friction, critical for consistent brake modulation under repeated thermal cycling. Stainless steel braiding withstands abrasion, vibration, and corrosive underbody environments, while the black vinyl outer sheath provides UV protection and identifies the hose line within engine compartments. At 18 inches, this length accommodates mid-range routing requirements in most custom brake installations without excess slack or tight bends that compromise hose lifespan.

Buyers assembling custom hydraulic brake systems, upgrading stock brake lines on performance vehicles, or fabricating competition-grade fluid delivery paths rely on this hose type to meet DOT brake system standards and handle the pressure spikes generated by high-performance calipers and master cylinders. The combination of braided reinforcement and PTFE lining makes this hose suitable for both street and track applications where fluid pressure consistency directly affects stopping power and pedal feel. This individual hose unit (sold as a single piece) integrates into larger brake system assemblies and is compatible with standard AN hose fittings used across the automotive aftermarket.
