WORM DRIVE HOSE CLAMP A worm drive hose clamp is a type of hose clamp that uses a metal band with a threaded screw mechanism to tighten around a hose, securing it to a fitting or pipe. The design allows for adjustable tension, ensuring a secure and leak-proof connection. Here’s how it works: The clamp consists of a band (usually made of stainless steel) that wraps around the hose. A screw mechanism, often located at one end of the band, tightens the band when turned. This screw is driven through the threads of the band, causing it to contract and securely grip the hose. The worm drive part refers to the specific thread design of the screw, which allows precise control over the clamp\'s tightness.
