#12 Female Swivel Connector

The #12 Female Swivel Connector from FRAGOLA (MPN 496112) is a critical adapter fitting for high-performance fuel, coolant, and hydraulic line systems in street machines, race cars, and custom engine builds. Designed for automotive professionals and enthusiasts who demand reliability under pressure, this swivel connector allows flexible line routing while maintaining secure, leak-free connections in tight engine bays and complex plumbing layouts where rigid lines would fail.

Constructed from lightweight aluminum and finished in blue anodized coating for corrosion resistance, the #12 Female Swivel Connector features a straight-through design that connects two 12 AN female ports without any flow interruption or pressure loss. The swivel end articulates independently, reducing stress on line connections during engine vibration and thermal cycling—a critical advantage in turbocharged and supercharged applications where traditional rigid adapters crack or loosen. The anodized finish protects against oxidation in harsh underhood environments while the precision-machined aluminum body ensures dimensional accuracy for dependable seal integrity at working pressures up to system specification.

This adapter is ideal for builders transitioning from hard-line fuel systems to braided stainless steel hoses, intercooler plumbing, transmission cooler circuits, and remote oil filter installations where port alignment is imperfect. The swivel design absorbs vibration better than fixed connectors, extending hose life and preventing micro-fractures at the fitting interface. At 0.17 lbs and compact dimensions (1.7 x 1.4 x 4.1 inches), the #12 Female Swivel Connector fits seamlessly into tight spaces without sacrificing performance—making it indispensable for modern engine bay layouts and restoration builds requiring OEM-quality reliability with aftermarket flexibility.
