Hoses & Fittings

A custom build is only as clean as its plumbing. Sloppy hose routing, mismatched fittings, and rubber hose held together with worm-drive clamps are the marks of an unfinished build. This collection covers everything needed to plumb any system on the vehicle correctly — AN fittings, braided hose, bulk hose, silicone hose and couplers, hose clamps, fuel hose, heater hose, radiator hose, hose ends, and all supporting hardware for leak-free, professional-grade installations.

AN fittings and braided hose are the standard for performance plumbing on fuel, oil, coolant, and brake systems. The AN (Army-Navy) standard provides a universal, leak-resistant connection system that's been proven in motorsport for decades. Stainless braided PTFE-lined hose handles fuel, oil, and brake fluid without degradation, and the stainless braid provides abrasion resistance and a finished appearance that rubber hose simply can't match. Aluminum AN fittings are available in straight, 45-degree, and 90-degree configurations in every AN size from -3 to -20, with adapters to NPT, ORB, and metric threads for integration with any component.

Hose ends — reusable and swaged — terminate braided hose runs cleanly and securely. Reusable hose ends allow field assembly and disassembly without special tooling, making them the choice for custom builds where routing may need to be adjusted. Swaged ends provide a permanent, factory-quality termination for production-style installations. Both styles are available in anodized aluminum in a range of colors for builders who want the plumbing to complement the engine bay aesthetic.

Silicone hose and couplers are the upgrade of choice for cooling system, intake, and intercooler plumbing. Silicone handles temperature extremes that rubber hose degrades under, maintains its shape under pressure, and is available in straight, elbow, and reducer configurations to suit any routing requirement. Color options — black, blue, red, and more — allow the cooling system plumbing to be integrated into the overall engine bay color scheme. Hose clamps in T-bolt and constant-tension styles provide secure, leak-free connections on silicone and rubber hose applications.

Bulk hose and fuel hose serve applications where braided AN line isn't required — vent lines, vacuum lines, low-pressure fuel connections, and general-purpose routing. Available in a range of diameters and materials, including ethanol-compatible fuel hose for builds running E85 or high-ethanol blends. Heater hose and radiator hose cover the cooling system connections that silicone couplers don't reach — available in OEM-profile and performance configurations.

This collection serves every type of build — full AN plumbing on a pro-touring or race car, silicone cooling system upgrades on a street rod, fuel system plumbing on a custom EFI build, or sourcing the right fittings to adapt between component thread standards on any platform.

AN plumbing assembly requires attention to thread engagement, proper hose end installation technique, and leak testing before pressurizing any system. Silicone hose installations should use T-bolt clamps torqued to spec for reliable sealing. Always verify hose and fitting compatibility with the fluid being carried — not all hose materials are compatible with all fuels and chemicals.

Shop the full Hoses & Fittings collection and plumb your build the way it deserves — clean, correct, and leak-free.
