Things You Will Need

+
  • Flat-head screwdriver
  • 5/16-inch hex-head nut driver

Tip

Worm gear drive clamps come in a wide variety of sizes for various application requirements. As such, the slotted hex-head of the worm gear screw may be a different size. Worm gear hose clamps are also available with a thumbscrew head for lighter applications that work at lower pressures or that are used for the binding of materials other than hose.

Warning

Always make certain that the worm gear clamp selected for use is designed for the particular amount of pressure in the application. Check with the local supplier of worm gear hose clamps for the proper size and type necessary.

  • Select the proper size worm gear hose clamp for installation. Match the type and size of the clamp to the diameter of the hose to be secured.

  • Open the worm gear hose clamp by turning the head of the worm gear screw counterclockwise. Use the screwdriver or a 5/16-inch nut driver until the worm gear screw threads are free from the slotted band.

  • Open the band by pulling it outward from the worm gear screw housing to the extent needed to fit around the hose.

  • Place the worm gear hose clamp around the hose to be clamped with the worm gear screw head facing in the direction necessary for access to the head with tools.

  • Insert the band into the worm gear screw housing until it stops and holds it firmly in place.

  • Turn the head of the worm gear screw clockwise to tighten using the screwdriver or the 5/16-inch nut driver. The worm gear screw meshes with the slots in the band to draw it tighter around the hose as the worm gear screw is turned.
