NAMZ Braided Brass Fuel and Oil Hose By the Foot
Braided brass hose is the detail that ties a custom build together — the warm metallic gleam against a raw frame or polished engine that tells anyone looking exactly how much care went into the work. NAMZ has been building these lines in the USA since 2002, and the Thermoid inner tube means the look never comes at the expense of durability.
