Performance & Practical Benefits

The 41582Q7 hose clamp provides secure, even pressure around the fuel line, ensuring a tight seal that won’t loosen over time. Its stainless steel design resists corrosion and holds firm even after repeated tightening or exposure to heat and fuel vapors.

Replacing worn or rusted clamps eliminates leaks and restores safe, efficient fuel delivery. This simple part adds confidence that your system is sealed tight, keeping fuel flowing where it should — not where it shouldn’t.

Why Buy OEM

Mercury’s Quicksilver 41582Q7 is a genuine OEM component, built specifically for Mercury’s gray 5/16-inch fuel line. Aftermarket clamps may not hold consistent pressure, may corrode quickly, or could cut into softer fuel hose materials.

OEM clamps are precision-sized and tested to maintain proper sealing force without damaging the hose, giving you the right balance of strength and flexibility. With Mercury, you get durability, reliability, and an exact fit that meets factory standards.
