Worm Gear Hose Clamps

Secure Hose Connections with Worm Gear Hose Clamps

Worm gear hose clamps, also known as worm drive hose clamps, jubilee clips, worm gear clamps, or simply worm clamps, are one of the most common types of clamps used in industrial settings. Known for their cost-effectiveness and reliability, these clamps are designed to provide an adjustable and easy-to-install connection on hoses. They are manufactured from various types of stainless steel, including marine-grade stainless steel, to help resist corrosion, which is essential in applications that are structured around moving or holding fluids or gases.

Worm clamps are designed with a captive worm gear screw attached to the steel band. The band features perforations that can either run the entire length or partial length of the band, depending on the application requirements. The threads of the worm gear screw mesh with the perforations in the band, forcing the band diameter to either increase or decrease as the screw is tightened or loosened.

Application Considerations

Before using a worm clamp, it is important to factor in elements of the application that may influence the clamp's performance.

Hose Size: While these clamps are adjustable, they do have a minimum and maximum internal diameter. Ensure you choose a clamp with a compatible hose size, factoring in any fluctuation due to pressure.
Hose Material: Check the hose material to make sure it is not too soft to become damaged by the clamp's perforations.
Space: Will you have space to install the hose clamp with a screwdriver? The worm gear screw must be tightened and loosened manually, so it is important to allow enough space for installation.
Environment: Will the clamp be exposed to additional corrosive elements, like weather, dirt and debris, extreme temperatures, etc.? Evaluate these factors so you know when to inspect and potentially replace your component.

Benefits

Worm gear hose clamps provide several benefits that make them a fastener of choice in hose applications.

Adjustable: The worm gear screw allows you to tighten and loosen the band to adjust the diameter and fit a range of hoses.
Reusable: As long as the clamp remains in good shape and does not sustain damage, it can be reused, making it a versatile component that is not deformed after use.
Durable: Made from various types of stainless steel, these clamps are designed to withstand corrosion from different kind of fluids and provide reliable connections.
Easy to Install: Installation requires a simple screwdriver for fast and convenient connections; for hard-to-reach spots, a hose clamp nut driver offers a flexible shaft to reach hex head screws in awkward spaces.
Economical: These affordable components combine ease, reusability, and durability to offer a reliable solution for a wide range of hose applications.

Difference Between a Spring Hose Clamp and a Worm Gear Hose Clamp

These two hose clamps differ in their design and installation. Spring clamps feature a band with open, vertical slots and metal tabs that, when squeezed together, open the clamp. When the clamp is placed over the hose, the tabs are released to compress the hose. They are sturdy components that work well when adjustability and controlled installation are not necessary.

Worm clamps feature horizontal slots and a worm gear screw that tightens or loosens the band to a controlled diameter, which is especially helpful when a hose diameter is not known beforehand. Both options are cost-efficient, reusable, and durable. Determine your application requirements before choosing the correct clamp.

Can You Overtighten Worm Clamps?

Yes, this can happen as a result of improper installation. It is important to know the required clamp compression before using this or any other type of clamp. Signs of an overtightened clamp could be limited flow in the hose, indentations at the connection point, and leaking liquid.

Screw-Type Stepless Worm Gear Hose Clamps

The screw-type stepless worm clamp is a variation of the standard worm clamp that offers a 360⁰ uniform internal diameter and eliminates the flat edge of the standard worm gear screw mount. The main advantage of this variation is that the compression is uninterrupted; the standard screw mount is not there to cause interference.
