48in #3 Line -3 Str/-3 Str

The 48in #3 Line -3 Str/-3 Str braided brake hose from ALLSTAR PERFORMANCE is engineered for builders and mechanics who demand reliability in custom brake systems. This 48-inch assembly suits applications requiring flexible hose runs between master cylinders, proportioning valves, and calipers—especially in modified vehicles where rigid tubing cannot safely navigate engine bays or suspension geometry. Whether you're fabricating a custom hot rod, restomod, or performance street machine, this hose accommodates the precise routing and vibration isolation that hydraulic brake systems require.

Constructed with braided stainless steel outer covering and a PTFE (polytetrafluoroethylene) inner liner, the 48in #3 Line -3 Str/-3 Str features 3 AN straight female adapters on both ends, allowing direct connection to 3 AN male ports without fittings. The PTFE core resists DOT brake fluid degradation and prevents corrosion from moisture intrusion, while the stainless braid provides abrasion protection and structural integrity under pressure cycling. The straight-to-straight configuration delivers a compact, low-profile design that simplifies installation in tight spaces where 90-degree or 45-degree elbows would create packaging conflicts or stress points.

Mechanics and fabricators working on custom brake system builds benefit most from this hose's flexibility and corrosion resistance. The 48-inch length accommodates mid-engine layouts, dropped frames, and custom master cylinder relocations without requiring excessively long runs that invite pressure loss or fluid degradation. Installation is straightforward—align the 3 AN straight female ends with your system's ported components and secure with appropriate AN wrench flats. For optimal performance, route the hose away from exhaust heat sources and sharp frame edges; support with P-clips at 12- to 18-inch intervals to eliminate chafing and vibration noise during acceleration.
