5/16in Polished Alum Line Clamps (6pk)

The EARLS 5/16 inch Polished Aluminum Line Clamps (6-pack) are two-piece hose clamps engineered for secure fluid line retention in high-performance fuel, oil, and coolant systems. This six-piece set delivers the compact, lightweight construction and corrosion-resistant finish demanded by engine builders, fuel system technicians, and motorsports enthusiasts who require dependable clamp performance without added weight.

The 5/16-inch inner diameter accommodates standard -4 AN hose sizes common in fuel rails, pressure lines, and return circuits. Polished aluminum construction minimizes corrosion in engine compartments exposed to moisture and vibration, while the two-piece design allows quick installation and removal without disturbing adjacent components. Each clamp in this set weighs just 0.16 lbs total, making it ideal for weight-sensitive builds where every ounce matters. The 1.75 x 1.15 x 3.9-inch package dimensions keep inventory footprint minimal in the garage or shop.

This clamp set suits fuel system work on street machines, race cars, marine engines, and hot rods where OEM plastic clamps or steel alternatives may lack aesthetic appeal or fail under heat cycling. Mechanics and fabricators frequently stock EARLS line clamps for custom fuel system builds, carburetor conversions, and retrofit plumbing where original equipment is unavailable or incompatible. Six clamps per pack allows coverage of multiple fuel lines in a single transaction, reducing reorder frequency on common applications.

EARLS is recognized throughout the performance automotive and aviation communities for precision hose and fitting components that meet or exceed industry reliability expectations. The polished finish on these aluminum clamps reflects professional craftsmanship and resists the degradation seen in painted or bare steel alternatives under underhood conditions, making them a practical choice for builds where longevity and appearance align.
