48in #3 Line -3 Str/90 Deg 3/8-24 Inv Flr

The 48in #3 Line -3 Str/90 Deg 3/8-24 Inv Flr brake hose assembly is purpose-built for high-performance and custom automotive hydraulic systems where precision, reliability, and compact routing are non-negotiable. Whether you're rebuilding a custom hot rod's brake lines, upgrading to a modern master cylinder setup, or fabricating a competition vehicle's stopping system, this 48-inch hose delivers the flex and fitment needed to navigate engine bays with tight packaging constraints. Designed for serious DIY mechanics and fabricators, it bridges the gap between OEM limitations and full-custom configurations.

This assembly features a 3 AN (3/16-inch nominal bore) braided stainless steel construction with PTFE (polytetrafluoroethylene) inner lining—a combination that resists abrasion, thermal cycling, and DOT brake fluid exposure far better than rubber hoses. The straight female fitting on one end mates cleanly to a caliper port or proportioning valve, while the 90-degree inverted flare male end (3/8-24 thread specification) locks into a master cylinder outlet or hard-line adapter with positive, leak-free engagement. The 48-inch length provides sufficient material for custom routing while remaining compact enough for most engine compartment layouts, and the braided outer jacket offers visual appeal alongside functional protection against puncture and wear.

This hose assembly excels in street rods, restomod builds, race cars, and any hydraulic application where OEM brake lines fall short or where routing demands flexibility. Its inverted-flare male fitting ensures compatibility with vintage and modern master cylinders alike, making it ideal for swaps or period-correct conversions. Installation requires basic wrench work—simply thread the male end into the master cylinder outlet and the female end onto your caliper or proportioning block, tighten to secure engagement, and bleed the system. The 0.26 lb weight makes it negligible in overall vehicle weight balance, and the compact 6-inch box dimensions ease shipping to your shop or garage.
