#10 Female Swivel

The EARLS #10 Female Swivel is a precision aluminum adapter fitting designed for high-pressure hydraulic and fuel line connections in motorsport, marine, and automotive applications. This straight 10 AN female-to-female swivel coupling allows hose terminations to rotate freely without twisting the line itself, reducing stress on fittings and preventing leaks during vibration-intensive operation. The blue anodized finish provides both corrosion resistance and easy visual identification in complex plumbing layouts.

The swivel design accommodates angular hose routing while maintaining full flow capacity across the 10 AN port size. Aluminum construction keeps weight minimal—critical in racing and performance applications where every fraction of a pound affects efficiency. The female-to-female configuration makes this adapter ideal for connecting two hoses with female AN fittings or as an intermediate coupling between male-threaded hard lines and female-terminated hoses. EARLS fittings are engineered to strict specifications and hold industry credibility for leak-free, durable performance under sustained pressure cycles.

This swivel adapter is essential for custom fuel systems, turbo coolers, transmission coolers, and hydraulic brake upgrades where hose routing requires flexibility and fail-safe connections. Motorsport builders, marine mechanics, and off-road fabricators rely on EARLS swivel couplings to handle the vibration, pressure spikes, and thermal cycling inherent to performance engines. Whether building a drag racing fuel system or a high-altitude off-road rig, the rotating connection eliminates the stress fractures that plague rigid plumbing.

Available as a single unit, this 10 AN female swivel is sold individually and easily integrates into existing 10 AN plumbing networks. The straightforward geometry and proven EARLS quality standard make it a reliable choice for rebuilds and OEM-equivalent repairs across countless performance platforms.
