Worm Gear Tube & Hose Clamps
Available325 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
