Double Wall-Clamp or Double Claw Clamp

The double wall (claw) clamp assembly to connect pairs of ISO flanges. Ease of use and economic make this the most commonly used configuration.


Bolted Nonrotatable

The two bolt flanges connected in the normal way.


Single Wall Clamp

Single wall clamps are used to join an ISO flange to a tapped flange on a pump, chamber or gate valve.


Bolted Rotatable

This fastening method allows the ISO flange to be rotated for ease of component alignment. Additionally, a rotatable bolt ring can be used to fasten an ISO flange to a non-­rotatable flange using bolt.

Applications for ISO vacuum components

*Roughing and foreline plumbing for large vacuum system.

* System requiring frequent cleaning.

* High vacuum, high conductance, inter-connections.

* Experimental system in research laboratories.

* Modular system which will be modified frequently.
