What are hose clamps used for?

Hose clamps are designed to secure a hose over a fitting, such as a spigot or barb, acting as a seal to prevent fluid from leaking at the connection. They also stabilize the hose connection. They’re predominantly used in the plumbing and automotive industries but are also used in other applications and to prevent leaks during the transport of liquids, chemicals and gases.

Applications and industries:

Specialty vehicle and automotive fuel lines, airlines, drain lines
Pumps and hydraulic systems in medical equipment (should NOT be used in other hydraulic-pressure applications)
White goods, venting systems and garden hoses
