4AN Fasteners/Clamps Black

The 4AN Fasteners/Clamps Black by REDHORSE PERFORMANCE represents a professional-grade hydraulic line management solution designed for high-performance automotive and motorsport applications. This set of 10 aluminum clamps with rubber lining is engineered to securely bundle and route hose lines while protecting them from abrasion, vibration, and impact damage during operation. Whether you're building a custom fuel system, brake line assembly, or transmission cooler setup, these fasteners provide the reliability demanded by fabricators, mechanics, and performance enthusiasts who require consistent, long-term line security.

Manufactured from lightweight aluminum construction with integrated rubber lining, the 4AN clamps offer superior vibration damping while maintaining minimal weight penalty—critical for racing and tuned applications where every component counts. The rubber interior layer prevents hose degradation from metal-to-rubber contact, extending hose life and reducing the risk of leaks caused by chafing. Each clamp in this 10-piece set is precision-engineered to accommodate 4 AN (5/16-inch) hose diameter, with a compact footprint measuring 3.8 x 1.5 x 5.2 inches, making installation straightforward in confined engine bays or chassis-mounted line runs. The black anodized finish resists corrosion and oxidation in harsh underhood environments.

Ideal for fuel injection systems, nitrous oxide lines, vacuum routing, and any pressurized fluid application, these clamps deliver OEM-equivalent durability at performance pricing. Installation requires basic hand tools and takes minutes per clamp, with no specialized knowledge needed. The rubber-lined design eliminates the need for separate protective wrapping, saving labor and ensuring consistent clamping force across your entire line assembly. For dedicated fabricators managing multiple vehicle projects or enthusiasts executing comprehensive system upgrades, this set of 10 provides ample coverage for typical builds while maintaining inventory for future work.
