A worm drive clip, also commonly known as a Jubilee clip, is a type of hose clamp used to securely fasten a length of tubing or hose pipe onto a suitable fixture. These clips are widely used in various applications to prevent leaks or tube detachment under high pressure.
Here are the key details about worm drive clips:
Design and Mechanism:
- A worm drive clip typically consists of a flat band made of materials like steel, nylon, or brass.
- The band is looped into a circle or band with a tightening mechanism on the outside.
- The tightening mechanism often includes a worm gear (sometimes called a worm drive Jubilee clip), which allows for easy adjustment and secure clamping.
How They Work:
- Worm drive clips are placed around the outside of the hose, where it joins with an outlet (such as a spigot, tap, nipple, or barb).
- The clip is then manually tightened using a screwdriver or hex key until it pinches the hose tightly around the joint.
- This minimizes the risk of leaks or detachment, especially under pressure.
Types and Variations:
- While Jubilee clip is technically a brand name, the term is often used generically for other makes of hose clips and band clamps.
- Some variations include spring clamps, wire clamps, and ear clamps, depending on the tightening method used.
- Cheaper models (like O-clips) lack a screw mechanism and require manual pinching or crimping to tighten.
Applications:
- Worm drive clips are used for securing hoses or tubing around outlets under pressure.
- They moderate pressures in various applications and can function as a type of compression or crimp fitting.
