4AN Push Lock Hose End s- Black 180

The 4AN push lock hose end in black 180-degree configuration is a critical fitting for any serious performance fuel system, oil cooling circuit, or hydraulic application where space constraints demand a sharp directional change. This 180-degree angled design allows you to run hard-line or braided hose past obstacles—engine bay geometry, firewall transitions, or tight suspension mounts—without sacrificing flow path efficiency or requiring additional adapters. Built for motorsports enthusiasts, street rod builders, and professional mechanics who demand reliability under pressure, this fitting eliminates the need for costly custom-bent hard lines or jury-rigged hose routing that compromises both appearance and durability.

The 4AN push lock hose end features aluminum construction with black anodized finish, offering both corrosion resistance and a clean, professional aesthetic under the hood. The swivel design on the female end reduces thread-stripping risk during installation and allows hose vibration to dissipate without transferring stress to the connected component—a detail that matters when you're running PTFE (polytetrafluoroethylene) hose at 100+ psi. Push-lock connection technology provides a secure, leak-free seal without the need for hose clamps, creating a streamlined appearance while improving system integrity; the 4 AN sizing handles flows suitable for fuel injection systems, auxiliary oil coolers, or power steering circuits on modified vehicles without bottlenecking.

This fitting is ideal for custom-built fuel systems in carbureted street rods, EFI conversion projects, auxiliary engine cooling loops, and high-output turbo applications where OEM plastic fittings won't suffice. The 180-degree angle pairs seamlessly with 4 AN PTFE braided hose, making it the standard choice when plumbing from tank to carb, turbo to oil cooler, or any hard-to-reach location requiring a sharp bend. Installation is straightforward: simply push the hose firmly into the fitting until it seats completely, and the internal barbs and o-ring seal ensure zero weeping. Its compact footprint (2.75 × 0.95 inches) fits tight engine bays without interference, and the black anodized aluminum finish resists fuel and oil while maintaining a professional appearance alongside other quality components.
