HWKG provides following american type hose clamp

Protective Teeth Worm Drive Hose Clamp

This american worm drive hose clamp comes with extra protective teeth. The structure blocks serrations and burrs on the steel band from tearing the hose when you fasten the clamp, reducing hose wear. It greatly lifts the long-term reliability and service durability of the pipeline connection.

Rubber Lined Worm Drive Hose Clamp

Fitted with a soft rubber lining, this worm drive hose clamp delivers dual advantages during installation. It prevents metal burrs on the band from abrading the hose surface, and significantly upgrades the sealing capacity of the hose clamp to eliminate liquid leakage, offering tighter, more dependable pipe joints.

Bushing Lined Worm Drive Hose Clamp

Its main function is to greatly increase the sealing performance of the clamp by adding a bushing accessory. It is suitable for scenarios where a high degree of sealing is required after installation, effectively preventing air and liquid leaks.
