#4 Str Hose End

The #4 Str Hose End from XRP-XTREME RACING PROD. is a precision-engineered fitting designed for high-performance fuel and brake line applications in modified vehicles and racing engines. This straight hose end adapter serves as the critical connection point between braided stainless steel hoses and fuel rails, carburetors, or brake components, making it indispensable for enthusiasts building custom fuel systems.

The #4 straight configuration refers to the AN (Army-Navy) size designation, which accommodates -4 braided hoses commonly found in fuel system upgrades. XRP's engineering focuses on reducing flow turbulence and pressure drops through streamlined internal passages, critical when supporting high-volume fuel pumps or complex multi-stage fuel injection systems. The hose end features a compact profile measuring 2.7 inches in length and weighing just 0.06 pounds, allowing integration into tight engine bay environments without sacrificing durability or performance.

This fitting is ideal for builders upgrading fuel systems in modified vehicles, ensuring leak-free, vibration-resistant connections under extreme operating pressures and temperatures. The straight design is preferred for inline fuel rail connections where space permits, offering maximum flow capacity and simplified installation during fuel system modifications.
