-4AN Female to -4AN Male 90 Degree Swivel Adapte

The -4AN Female to -4AN Male 90 Degree Swivel Adapter from VIBRANT PERFORMANCE is a precision-engineered fitting designed for serious automotive hydraulic and fuel system builds. This adapter solves a critical plumbing challenge: redirecting AN-rated hose lines at sharp angles without compromising flow or creating stress on adjacent components. Whether you're laying out a custom fuel system, cooling circuit, or brake line arrangement in a high-performance engine bay, this 90-degree swivel connector allows you to navigate tight spaces and avoid kinks that would otherwise restrict flow or fail under pressure.

Constructed from lightweight aluminum and finished in durable black anodize, the -4AN Female to -4AN Male 90 Degree Swivel Adapter delivers both strength and corrosion resistance essential for underhood environments. The swivel design is the key advantage here—unlike fixed 90-degree elbows, the male fitting rotates independently, allowing final hose positioning without twisting the adapter itself or creating torque on connected fittings. This reduces the risk of leaks at seals and prevents loosening over thermal cycles and vibration. The -4AN (JIC 37-degree flare) standard ensures compatibility with industry-standard braided stainless hoses and matching fittings, maintaining full system integrity under pressure.

Fabricators and engine builders rely on swivel adapters like this when space constraints or hose routing geometry demands a bend that a straight fitting cannot accommodate. It's equally at home in fuel cell installations, intercooler plumbing, custom cooling loops, and transmission cooler circuits—anywhere precision line management prevents collateral damage to wiring harnesses or engine components. Pair it with matching -4AN hose and fittings for a leak-free, vibration-resistant connection that performs reliably in both street and competition applications.
