6AN Fasteners/Clamps N/A

The REDHORSE PERFORMANCE 6AN Fasteners/Clamps are professional-grade push lock hose clamps engineered for high-pressure fuel, coolant, and fluid line applications in modified and performance vehicles. Designed for mechanics and enthusiasts who demand reliability in their engine bay modifications, this stainless steel clamp pair delivers the secure, vibration-resistant clamping required when upgrading to aftermarket hose systems, fuel rails, and custom cooling configurations. Whether you're building a turbocharged engine, installing a fuel surge tank, or routing AN lines through a custom intake manifold setup, these fasteners provide the dependable hold that keeps high-flow systems leak-free under boost and sustained RPM loads.

The 420 Series band clamp operates on a proven push-lock mechanism that eliminates the need for constant wrench adjustments—a critical advantage in tight engine compartment layouts where traditional worm-gear clamps become difficult to service. Manufactured from marine-grade stainless steel, the natural finish resists corrosion from fuel additives, coolant chemistry, and moisture exposure, ensuring longevity in both street and track environments. The 6 AN sizing matches standard -6 AN hose diameters and fittings, providing a proper squeeze pressure that prevents weeping at threaded connections while avoiding the over-tightening damage that can occur with improper clamp selection. This pair configuration allows dual-line installations common in dual-fuel systems, auxiliary cooler loops, or redundant pressure lines in high-performance fuel delivery setups.

Performance builders, turbocharged engine shops, and fuel system fabricators rely on REDHORSE Performance clamps for OEM-equivalent security in custom applications where standard hardware is insufficient. The compact footprint—measuring 2.8 x 1.05 x 3.8 inches per clamp—fits efficiently in congested engine bays where larger band clamps would interfere with intake runners, ignition coils, or intercooler piping. Installation is straightforward: slide the clamp over the hose-to-fitting interface and engage the push-lock collar until it clicks, creating a vibration-dampened seal that remains stable through thermal cycling and boost events. Compatible with any -6 AN hose rated for your system's pressure specification, these clamps are suitable for fuel systems, coolant loops, brake fluid lines, and transmission cooler circuits in street cars, drag vehicles, and road-course platforms.
