The Speedmaster 1-339-007-05 is a -4 AN braided black nylon hose line supplied in a generous 20-foot length, giving you plenty of material to route fuel, oil, or other fluid lines cleanly throughout your build. The black nylon braiding delivers a clean, finished appearance while helping protect the inner hose from abrasion and everyday engine-bay wear.
Sold as a 20 ft. continuous length, this hose is compatible with standard -4 AN fittings, making it a straightforward choice for custom plumbing projects where a precise fit and a professional look are priorities. Cut to your exact needs and pair with your preferred -4 AN end fittings for a complete, leak-resistant fluid line assembly.
