Flange connections High vacuum tight connection of two flanges is achieved by inserting a seal (centering ring and O-ring).
	Clamp Flange to Clamp Flange Connection with clamps and screws which fit to the groove of the clamped flanges.
	1 Clamp Flange
	2 Clamp Bolt
	3 Seal
	Clamp flange to rigid flange For this connection an overthrow flange with retaining ring is used. The retaining ring is pressed into the outer groove of the clamped flange thus fixing the overthrow flange to the clamped flange. The holes are lined up with the opposite rigid flange. Both flanges are bolted together.
	1 Clamp Flange
	2 Overthrow Flange
	5 Locking Flange
	Clamped flange to base blate Claws which fit in the groove of the clamped flange and bolts are used for this connection.
	1 Clamp Flange
	6 Locking Flange
	7 Threaded Base Plate
