Ideal Vacuum Cube Conductance Limiting Coupler Kit Joins Two 6 x 6 in. Cube Frame Faces, Includes Hardware and Seals.

This 6 x 6” Cube conductance limiting coupler kit allows two Cube frames to be tightly joined face-to-face on their 6 x 6” faces with a conductance-limiting orifice between them. A diagram of how to use this coupler is shown as the second image above.

This kit consists of a 6061-T6 aluminum Cube conductance limiting frame coupler with two O-rings, several 304L stainless steel barrel type, coupling draw bolts, and the hardware and seal needed to mount a conductance limiting orifice insert plate. The frame coupler is sandwiched between the two Cube frames and acts just like a flange centering ring. The coupler makes the seal between the two Cube frames and uses the patented Ideal Vacuum Taper-Seal™ design. The draw bolts rigidly clamp the two Cube frames together.

The frame coupler has a full orifice diameter of 2 inches. Restrictive inserts are available with orifices of 0.5, 1.0, 1.5, and 2.0 mm diameter. These smaller orifices greatly restrict the flow of gas between the two coupled vacuum chambers.

This coupler kit combined with an orifice plate allows two chambers to be held at different vacuum levels with a slow flow of gas between them. Due to the long path length of the orifice relative to the orifice diameter, the gas exits the lower pressure side as a tightly focused beam. Applications include calibration of precision valves and flowmeters, residual gas analysis, and molecular beam spectroscopy.
