Product Listing

Claw -clamp

Double claw-clamp assemblies are commonly used for making vacuum seal connections. Assembly is simplified by the 360° rotatable flanges and the self-centring feature of the centring ring. Single claw-clamp assemblies are used to mate a clamp-style to a threaded bolt-style such as on a gate valve. The vacuum seal is made by compressing the 0-ring between the mating flanges. This is done by alternately spanner-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 centring ring.
