Inlet Swivel Fitting 90 Deg Male 4an

The Inlet Swivel Fitting 90 Deg Male 4AN is an essential hydraulic and fuel system component engineered for racing, high-performance street builds, and serious off-road applications. Built by TILTON, a manufacturer with decades of racing heritage, this swivel fitting solves the real-world problem of hose routing in tight engine bays where rigid plumbing won't fit. Whether you're upgrading a brake system, fuel delivery setup, or custom coolant circuit, this adapter allows hose lines to articulate without kinks or stress concentrations that compromise flow and longevity.

The 90-degree male swivel design uses a rotating ball joint that permits ±45 degrees of angular movement while maintaining a sealed connection. The 4AN port size (approximately 1/4-inch NPT equivalent) handles moderate flow rates typical of fuel systems and auxiliary hydraulic circuits in performance vehicles. The swivel mechanism is precision-machined from aluminum or ductile iron, minimizing weight while resisting vibration-induced loosening—critical for engines that see sustained high RPM. The 90-degree inlet orientation allows hose entry perpendicular to the component axis, reducing bend radius requirements and preventing hose abrasion against frame rails or block surfaces.

Mechanics and fabricators install this fitting on fuel pressure regulators, accumulator tanks, remote filter heads, and custom fuel rails where space constraints demand flexible routing. The male 4AN threads accept standard -4 AN hose ends (both straight and 90-degree) at the source side, while the swivel outlet connects to larger diameter hard lines or additional hose runs downstream. Confirm your hose sizing and thread pitch before ordering; this fitting is compatible with 4AN -4 male fittings and accepts standard 37-degree JIC or NPT sealing surfaces depending on your system design.
