Overview

Hose clamps are a device used to attach and seal a hose onto a fitting. They are essential for maintaining a connection by preventing the hose from slipping off the fitting. Hose clamps come in various designs and sizes, each suited for different applications and hose types. 

Hose Clamp Applications

Hose clamps are used across a variety of industries including agriculture, automotive, and industrial. In the agricultural industry, hose clamps have to withstand harsh environmental conditions and heavy use to connect irrigation hoses and other equipment. For the automotive industry, clamps secure fuel lines, coolant hoses, and air intake systems to ensure contents remain contained and systems operate efficiently. Manufacturing and processing plants use industrial hose clamps to connect various hoses to machinery and equipment, playing a key role in maintaining safety and efficiency.  

Types of Hose Clamps

There are six main types of hose clamps: band, bolt, ear, spiral, T-bolt, and worm gear. 

Band Clamps

Band clamps are suitable for large-diameter hose and are often used in agricultural and industrial applications. When using more than one band clamp the clamps should be offset around the hose by at least 90°, preferably 180°. This helps distribute the clamping force more evenly and to help prevent potential line leaks under the buckles. A band clamp hand tool is used for application.

Bolt Clamps

Bolt clamps, available in both single and double bolt styles, are designed to bend while tightening. The bolts bend around the hose when it reaches the recommended torque rating, and the clamp halves conform to the shape of the hose while tightening. Bolt clamps are for single use only; they cannot be reused.

Ear Clamps

Also called pinch-on clamps, ear clamps are single-use clamps crimped onto a hose using special tools. They provide a tight, permanent seal and are ideal for applications where the clamp will not need to be removed.

Spiral Clamps

Spiral clamps are used on convoluted cover hose. The wire drops into the groove of the convoluted cover for secure clamping. The helix spirals on the hose can wind clockwise or counterclockwise.

T-Bolt Clamps

T-bolt clamps get their name from the T-bolt that is used with a hex nut to tighten the clamp. These clamps provide a strong, uniform seal and can be reused.  

Worm Gear Clamps

Worm gear clamps are another common type of clamp. They feature a slotted band and screw mechanism. When the screw is turned it tightens the clamp around the hose providing a secure grip. Worm gear clamps are ideal in applications where the hose may need to be removed often as the screw mechanism allows for easy adjustment or tightening.

Choosing the Right Hose Clamp

Selecting the proper hose clamp involves considering several factors.

  • Application: Different clamps are designed to meet different needs, so consider the specific requirements such as pressure, temperature, and exposure to chemicals.
  • Material: What material is best suited for the application? Clamps are typically offered in stainless steel and galvanized steel. Stainless steel is preferred for its strength and resistance to corrosion, especially in harsh environments.
  • Size: The clamp must fit the hose diameter correctly. If the clamp is too large or too small it will not provide a secure seal.
  •  Installation and Removal: Will the clamp need to be removed? Some clamps are easy to install and remove, while others are single use only.
