A hose clamp (or hose clip) is a specialized fastener designed to secure a hose or flexible tubing onto a specific fitting or raccord. It acts as the critical sealing component, preventing the leakage of liquids, gases, or compressed air within a pressurized system.

These clamps are available in various types and application methods to suit different industrial or domestic needs. They are primarily categorized into two groups:

1. Screw-type Hose Clamps

Standard screw-type clamps, often called worm-drive hose clamp, are typically used for medium to high-pressure applications. Their robust design allows for a high-torque leak tight sealing and consists of three main components:

Housing (or Cage)
Band (or Strip)
Screw

2. Screwless Hose Clamps

Screwless clamps, like ear clips, are the ideal solution for quick assembly and low-pressure requirements. These are applied using specific tools, such as manual, pneumatic, or electric pincers. They provide a uniform, tamper-proof seal in high-speed production environments.

Beyond sealing, metal clamps also function as versatile fastening elements, ensuring a solid and durable application between two separate components.
