#10 90 Deg Dbl Swivel Hose End to #12 Nut

The #10 90 Deg Dbl Swivel Hose End to #12 Nut is an essential fluid-transfer adapter designed for high-performance fuel, coolant, and brake line applications in modified and stock vehicles. This double-swivel fitting addresses a common challenge faced by engine builders and transmission specialists: achieving flexible, leak-free connections in tight engine bays where rigid hard lines simply won't fit or align properly.

Whether you're fabricating a custom fuel system for a turbo build, rerouting brake lines around new components, or adapting OEM hydraulic lines to aftermarket manifolds, this hose end delivers the angular and rotational freedom necessary to eliminate stress on connections and prevent catastrophic leaks under pressure. The dual-swivel design allows the fitting to rotate 360 degrees at both the hose end and the nut connection points, absorbing vibration and thermal expansion without transmitting load to nearby components.

The #10 inlet accommodates standard -10 AN hose, while the #12 outlet threads into -12 AN ports or 3/4-inch NPT adapters commonly found on fuel rails, block fittings, and cooler inlets. The 90-degree configuration provides space-efficient routing through congested engine compartments, and the precision-machined aluminum or steel construction ensures reliability under pressure cycles. Swivel fittings are particularly valuable in custom fuel systems, turbo builds, and EFI conversions.
