Zinc Plated Double Ear Hose Clamp

Zinc-Plated Double Ear Hose Clamp is a type of lightweight, economical, and fast-installing constant-tension clamp. Featuring a distinctive two-ear design and lacking a screw or worm gear, they rely on a simple yet effective spring-steel construction to provide a reliable seal for low-to-medium pressure applications. The zinc plating offers a basic level of corrosion protection for general-purpose use.

Features of double ear hose clamp

Material & Finish:

Base Material: Typically made from spring steel.

Finish: The clamp is coated with a layer of zinc plating (often via electroplating). This provides a sacrificial barrier against rust and corrosion in standard, non-severe environments (e.g., indoor use, protected engine bays). It is not suitable for prolonged exposure to saltwater, strong chemicals, or highly corrosive atmospheres.

Screw-Less, Spring-Action Design:

The clamp functions as a pre-tensioned circular spring.

It applies a constant, preset clamping force that can accommodate minor changes in hose diameter due to temperature fluctuations, helping to maintain the seal.

Contains no moving parts like screws or worms, making it inherently resistant to loosening from vibration.

Double-Ear Mechanism:

The defining feature is the two opposing "ears" or "lugs" protruding from the clamp band.

These ears are squeezed together using specialized pliers (e.g., hose clamp pliers, pinching pliers) to open the clamp for installation over a hose and fitting.

Once the pliers are released, the inherent spring tension of the steel forces the ears apart, contracting the band tightly around the hose to create the seal.

Typical Applications of double ear hose clamp

These clamps are commonly used in cost-sensitive, high-volume manufacturing where the environment is relatively controlled:

Automotive OEM: Lower-temperature coolant hoses, heater hoses, air intake ducts, and vacuum lines.

Appliance Industry: Drain hoses, water inlet/outlet connections on washing machines, dishwashers, etc.

General Consumer Products: Lawn and garden equipment, small engines, and furniture.

Low-Pressure Industrial Ducting & Connectors.
