Description:
Double ear hose clamp/double eaar hose clips a type of hose or pipe clamp designed for secure fastening using a double-ear (two-lug) mechanism made from zinc-plated steel. The 2 ear clamps are high-strength metal clamp used to fasten hoses, pipes or cables. It achieves uniform pressurization and firm locking by tightening the ears on both sides. Compared with ordinary hose clamps, the double-ear structure provides higher vibration resistance and sealing, and is widely used in automobiles, ships, industrial equipment and other fields.
Material:
W1 - all parts carbon steel with zinc plated
Features:
Double ear hose clamp provides superior sealing performance through their 360-degree compression design. The twin-ear configuration allows for even pressure distribution around the entire circumference of the hose or pipe, creating a leak-proof connection that outperforms standard single-ear clamps in high-pressure applications. This makes them ideal for fuel systems, coolant lines, and industrial fluid transfer where sealing integrity is critical.
The smooth, uninterrupted band design eliminates protruding screws or sharp edges found on other clamp types. This clean profile reduces injury risk to technicians and prevents damage to surrounding components from abrasion. The flush surface also makes these clamps easier to clean and sanitize for medical or pharmaceutical applications.
Available in a wide range of diameters, double ear hose clamp accommodates everything from small-bore medical tubing to large industrial hoses.

Application:
Double ear hose clips are widely used in fuel systems, coolant lines, and air intake hoses due to their vibration-resistant design. They provide secure, leak-proof connections in cars, trucks, motorcycles, and marine engines, preventing fluid leaks under high-pressure conditions. OEM manufacturers prefer them for EV battery cooling systems and turbocharger piping because of their consistent clamping force.
In pneumatic, hydraulic, and chemical transfer systems, double ear hose clips ensure reliable sealing for high-pressure hoses, compressed air lines, and fluid connectors. Their corrosion-resistant stainless steel construction makes them suitable for oil & gas, mining, and heavy machinery, where harsh environments demand durable fastening solutions.
