4AN Non-Swivel Hose En ds Black 45

The 4AN Non-Swivel Hose Ends Black 45 from REDHORSE PERFORMANCE is a precision hydraulic fitting designed for high-performance fuel and coolant delivery systems in modified vehicles. It is ideal for automotive enthusiasts who require reliable, leak-free connections in custom engine bays, turbo setups, and fuel system upgrades.

This fitting eliminates the need for additional adapters or swivel components, providing a fixed, secure connection point that won't rotate under vibration or system pressure. The 45-degree angle design allows for flexible routing around engine bay obstacles without kinking or restricting flow. Constructed from high-grade aluminum alloy with a durable black anodized finish, it resists corrosion from coolant additives and fuel solvents.

Professional engine builders and DIY tuners can benefit from the non-swivel design, which reduces micro-movements that can fatigue hose ends over time. This results in a longer service life and fewer leak points in your custom fuel and coolant systems. The 4AN size is commonly used in medium-duty applications, offering a balance between flow capacity and compact installation footprint.
