A hose clamp is a fastening device used to secure a hose onto a fitting, such as a nipple or pipe. It prevents the hose from slipping off or leaking under pressure.

Worm drive (screw) clamps: The most common type, adjustable with a screw mechanism.
Ear clamps: Tightened with special pliers, often used for permanent installations.
Quick-release clamps: Can be fastened by hand, ideal for temporary connections.
T-bolt clamps: Heavy-duty clamps for high-pressure applications, such as in engine systems.

It depends on the application. Stainless steel: Best for corrosive environments (outdoor, marine, agriculture). Galvanized steel: Suitable for simple indoor applications. Plastic clamps: Used for low-pressure systems or where electrical insulation is needed.

Choose your hose clamp based on: The outer diameter of the hose (measure before selecting). Pressure and environment (indoor, outdoor, chemical exposure). Type of load (stationary vs. vibration/movement) - Make sure the clamp’s adjustable range fits the hose size and that the material is appropriate for the intended environment.
