Earl's Swivel-Seal hose ends feature a military-specification hard-anodized aluminum finish that penetrates the surface for superior wear and corrosion resistance. Manufactured from aerospace-proven materials and precision-machined to exact tolerances, these hose ends provide strength, durability, and reliable performance in demanding fluid systems. The nipple-and-cutter design and dual-plane anti-seepage seal help prevent leaks, while the optimized bent-tube design promotes excellent fuel flow. Stainless steel retention pins allow 360-degree adjustment after installation for flexible hose routing. The hard-anodized finish also helps reduce thread galling and provides resistance to alcohol-based fuels.
