45 Degree Hose End Fitti ng; Hose Size: -4AN

The VIBRANT PERFORMANCE 45 Degree Hose End Fitting for -4AN hose is a precision-engineered adapter designed for high-pressure fluid transfer systems in performance and racing applications. This swivel fitting accommodates 4 AN hose to 4 AN female connections, allowing directional flexibility in tight engine compartments and custom plumbing layouts where 45-degree routing is necessary to avoid pinching, kinking, or interference with surrounding components.

Constructed from aluminum and finished in black anodize, this fitting balances weight savings with corrosion resistance in high-temperature and high-vibration environments. The swivel design eliminates the need for secondary wrench flats during hose installation, reducing assembly time and the risk of over-torquing the connection point. The 45-degree geometry is critical for applications where parallel or 90-degree fittings would create dead-leg sections or restrict flow, such as fuel delivery lines, coolant bypass circuits, and custom oil cooler setups. The black anodized finish maintains appearance while providing a protective oxide layer against oxidation.

This adapter is essential for builders and technicians configuring custom hydraulic and fluid systems where space constraints demand angled connections. VIBRANT PERFORMANCE fittings are widely used in automotive performance, marine, and industrial cooling applications where reliability under pressure and vibration is non-negotiable. The -4AN sizing handles moderate to high flow rates suitable for most street and track applications without excessive pressure drop.

Sold as a single unit, this hose end fitting integrates seamlessly into existing AN-based plumbing systems and pairs with VIBRANT PERFORMANCE hose assemblies and complementary fittings across their comprehensive catalog of 45-degree, 90-degree, and straight configurations.
