- [What are the different types of worm clamps?](https://hwkg.com/what-are-the-different-types-of-worm-clamps/): A worm clamp is a metal band that a screw tightens. The screw fits into slotted threads. It seals hoses onto fittings. Turning the screw pulls the band tighter around the hose. This presses the hose against the fitting underneath. The pressure and friction create a seal. This seal stops fluids or gases from escaping, even when system pressure changes. These worm clamps can be reused and adjusted, unlike pinch clamps that are used once. They work in plumbing, automotive, and industrial systems. What types exist, and how do you choose the right one? This post answers that question.
