  • Fastens ISO LF Large-Flange™ of comparable size
  • Quick make and break
  • Zinc plated steel bolt
  • Aluminum claw construction
  • Requires centering ring with elastomer gasket

Double Claw-Clamp Assemblies are commonly used for making Large-Flange™ vacuum seal connections.Assembly is simplified by the 360º rotatable flanges and the self-centering feature of the centering ring.
Single Claw-Clamp Assemblies are used to mate a clamp-style Large-Flange™ to a threaded bolt-style Large- Flange™, such as on a gate valve.
The vacuum seal is made by compressing the O-ring between the mating flanges. This is done by alternately wrench-tightening opposing pairs of clamps until the first metal-to-metal contact is made between the inner surfaces of the flanges and the spacing lip of the centering ring.
