Zinc Plated Fuel Injection Hose Clamps

Zinc Plated Fuel Injection Hose Clamps are specialized, high-strength worm drive clamps designed to meet the demanding requirements of modern fuel injection systems. These clamps are engineered for high-pressure, high-vibration applications where the risk of fuel seepage or vapor loss must be eliminated. The zinc plating provides a corrosion-resistant finish suitable for standard underhood environments

Key Features of fuel injection hose clamps

High-Strength Design

Band: Manufactured from a thicker, high-grade steel band compared to standard clamps. The band is wide (typically 9mm-12mm) to distribute clamping force evenly.

Perforations: Features rolled or folded perforations, creating a smooth inner band surface. This is critical to prevent cutting into high-pressure rubber or reinforced fuel hoses, especially during tightening.

Worm Drive: Utilizes a heavy-duty hex socket drive screw (e.g., 6mm or 7mm head) instead of a slotted screw. This allows for higher, more controlled torque application using a socket wrench, ensuring a secure, leak-proof seal.

Housing: Features a robust, four- or six-sided saddle that fully encloses the screw, preventing it from "rolling over" under high torque.

Material & Finish

Base Material: Made from high-carbon steel or alloy steel for superior tensile strength.

Finish: Coated with a layer of zinc plating (often yellow or clear chromate). This provides effective corrosion protection for most automotive underhood applications where direct exposure to road salt or extreme chemicals is limited. It is a cost-effective alternative to stainless steel for OEM use.

Primary Advantages of fuel injection hose clamps

High-Pressure Sealing: Specifically engineered to withstand the continuous high pressure (often 50-100+ PSI) and pulsations of fuel injection systems without leaking or loosening.

Superior Vibration Resistance: The robust design and hex drive prevent self-loosening in high-vibration engine environments.

Hose-Safe Design: The smooth, rolled edges of the perforations protect the integrity of expensive fuel injection hoses.

Controlled Torque Application: The hex socket allows for precise tightening to a specified torque with the correct tool, preventing under- or over-tightening.

Reliable & Durable: Offers a long service life in its intended application, providing a secure, maintenance-free connection.

Typical Applications

Primary Fuel Lines: Connections between the fuel rail, fuel filter, and high-pressure fuel pump.

Return Lines: On systems with a fuel pressure regulator on the return side.

Diesel Fuel Systems: Common on diesel injection lines.

High-Pressure Power Steering Lines: Where similar pressure and vibration resistance are required.
