12an Straight HS-79 Hose End

The 12AN Straight HS-79 Hose End from XRP-XTREME RACING PROD. is a precision-engineered fitting designed for high-performance fuel, oil, and coolant systems in modified vehicles and race engines. Built for automotive enthusiasts who demand reliability under extreme pressure and temperature conditions, this straight hose end connects braided stainless steel hoses to carburetors, fuel pumps, radiators, and transmission coolers. Whether you're building a turbocharged street engine, preparing a track-focused machine, or upgrading a classic hot rod's fuel delivery system, this fitting delivers the durability and leak-free performance that separates amateur builds from professional-grade installations.

The HS-79 designation reflects XRP's proven hose-end design that accommodates 12 AN (3/4-inch nominal) braided lines, a standard choice in high-flow applications where 6 AN or 8 AN fittings would create bottlenecks. The straight configuration eliminates the need for additional elbows, reducing potential failure points and simplifying routing through tight engine bays. Machined from aerospace-grade materials with a micro-polished finish, this fitting withstands sustained pressures in fuel injection systems, bypass circuits, and boost-controlled applications without thread stripping or weeping. The swaged connection ensures repeatable, tool-free assembly once properly seated, while the precision-cut AN threads guarantee compatibility with all standard -12 hose sizes and male-threaded ports found across the motorsports industry.

Mechanics and engine builders favor the 12AN Straight HS-79 Hose End for fuel system plumbing in EFI conversions, dual-pump fuel setups, and transmission cooler installations where straight runs eliminate crimped bends that reduce flow and invite failure under boost. Its compact footprint (2.7 x 1.35 x 3.05 inches) fits tight spaces without requiring custom fabrication, and the minimal weight penalty (0.09 lbs) makes it ideal for weight-conscious builds. Installation requires only a wrench and proper hose preparation; compatible with all -12 braided PTFE and stainless lines. For street cars, circle-track racers, and weekend warriors who refuse factory-grade components, this hose end delivers the precision fit and proven reliability that prevents expensive system failures mid-season.
