Order LookupWorm Gear Tube & Hose Clamps
Available314 products
Worm gear clamps, also called worm drive clamps, secure tube and hose connections to ensure a tight fit and prevent fluid and air from leaking. They’re called worm gear clamps because of the housed, helical-threaded screw that engages with the slots in the band and tightens the band as the screw turns. Worm gear clamps are non-permanent and remove in the same way they are installed, easing maintenance. They are used in a variety of automotive and industrial applications to secure hose and tube connections.
Standard Worm Gear Clamps
These standard worm gear clamps are useful in general purpose applications to secure tube and hose connections. A hand tool such as a hex-nut driver or screwdriver tightens the clamp.
