The entry point for the feedthrough must be vacuum-sealed via a suitable through hole. The feedthrough can be connected to a CF vacuum flange.\u003c\/p\u003e\n\u003ch3\u003eCommon Types of Feedthroughs\u003c\/h3\u003e\n\u003cp\u003eCF Conflat flanges are normally for processes requiring ultra high vacuum pressures, \u003cspan\u003edown to 10\u003c\/span\u003e\u003csup\u003e-12\u003c\/sup\u003e\u003cspan\u003e Torr\u003c\/span\u003e\u003csup\u003e \u003c\/sup\u003e, and are vacuum sealed via nuts and bolts with copper gaskets.
