15in #4 Line -4 Str/-4 90 Deg Tube Style 5pk

The ALLSTAR PERFORMANCE 15-inch #4 Line -4 Straight/-4 90 Degree Tube Style hose fittings are essential components for custom fuel and coolant line routing in high-performance automotive builds. This five-pack configuration is designed for mechanics and engine builders who require reliable, leak-free connections in modified engines, fuel systems, and cooling circuits.

These fittings feature a -4 AN (1/4-inch) port size and include both straight and 90-degree configurations, providing flexibility in line routing without needing separate orders. The tube-style design accommodates hose barbs or compression-style connections based on your line preference and application requirements.

Ideal for engine builders completing LS swaps, carbureted fuel system upgrades, and custom radiator and heater hose layouts, these fittings are also suitable for complex plumbing in turbocharged or supercharged installations. The compact package weight of 0.82 lbs makes this five-pack highly portable for mobile fabrication shops and race trailers, ensuring you have the necessary components on hand for your projects.
