Worm-Drive Hose Clamps

In stock

Worm Drive Hose Clamps, also know as Worm Gear Hose Clamps, are a metal band clamp. They feature a helical-threaded screw, or worm gear, that is housed in the clamp.

Worm Gear Clamps provide a hi-torque clamp that prevents hose connections from slacking, and they also prevent leakage. When the included screw is turned on the clamp worm drive, it acts like a worm drive pulling the threads of the band. This causes the metal band to tighten around the hose or tube. Alternatively, when turning the screw in the counter direction, the band will come loose.

Our range of Worm-Drive Clamps have an interlocked back to prevent shearing. The band detaches from the housing so you can install or remove them without disconnecting the hose or tube. The worm-drive hose clips can be used to secure any of our Hose Protection Sleeves, found in our Hydraulic Hose Protection category. These worm gear clamps are sized to SAE standards.

  • Materials; Stainless Steel worm drive hose clamps and Carbon Steel worm drive hose clamps
  • Screw is the same material as the worm gear clamp.
