What to Check in a Dryer Hose Clamp

Quality clamps will keep your hose in its place and will not create an opening for a leak to happen. To make sure you get the right strap for your ducting system, be sure to keep in mind the following factors:

  • Screw this part is responsible for tightening or loosening a clamp. Clamp’s with worm drives are usually great at keeping the hose in its place and is less likely to loosen up for a long period. However, they can require hand tools to turn the screw. Plastic thumbscrews remove the need for tools, which makes them easier to detach and reattach when you need to clean the hose. On the other hand, the plastic material may snap and leave you with a broken clamp.
  • The material clamp is made from different materials. The most common ones are steel straps, which has a decent durability and lifespan. Some can even resist corrosion and rust. Other clamps are made from plastic that are naturally rustproof and nonconductive. However, they are not as durable as the metallic straps.
