Types and uses of Hose Clamps

Hose clamps are used for a variety of applications. To suit different purposes, they come in different shapes and sizes. Hose clamps are commonly used for low-end applications like fixing a garden hose to high-end applications like fixing automotive repairs in a car. They find place in household repairs, especially in fixing plumbing problems and for attachments on various equipments. Based on the application and materials used, hose clamps are of different types such as heavy duty, Hydraulic, large clamps, plastic clamps, quick release and stainless hose clamps. Basically, they are classified as,

Screw clamps:

Screw clamps are also called as band clamps or worm drives that are made up of a stainless steel or galvanized steel band. This has a thread pattern similar to that of a screw. The screw is at one end of the clamp and the clamp is placed on the hose that requires to be connected. The other end of the band is then fixed in the space between the screw and the band. The band is then tightened by turning the screw that fixes onto the threads that are imprinted on the band. Thus the entire clamp is tightened.

Uses:

They are used for household works like domestic wastewater piping and other similar jobs where the pipes need a more flexible connection.

Spring clamps:

These clamps are made of spring steel band. It has one side cut and a narrow point at one end of the clamp and two narrow points on the other end. The pointed piece bends outward and rolls the band into a ring while the protruding pieces intertwine with each other. As the pointed pieces are pressed together, the ring widens and allows the clamp to slip over the hose to secure it. As there is a release of pressure, the ring tightens and stays on the hose.

Uses:

They are used mainly in automotive cooling system hoses.

Wire clamps:

These clamps are made up of heavy steel band. The band is bent into a U-shape and molded into a ring with the ends overlapping each other. There is a captive nut attached to one end of the clamp. The overlapping ends are bent outwards with the captive nut at the one end of the clamp and a captive screw attached to the other end. The screw is turned in the nut, the clamp is tightened to the desired size.

Uses:

These are used to secure the radiator hose on automotives.

Ear clamps:

These are made up of stainless steel which is shaped into a ring and has two ears that extend from the clamp. On fixing the clamp on the hose, it is tightened by crimping the ears which is facilitated by a crimping tool. This causes the clamp to contract around the hose to secure.

Uses:

They are used to seal hoses and tubes in order to prevent the seeping of liquid and gas.
