An elastomeric gasket can be made of , fluoropolymer, or. Metal gaskets are used in ultra-high vacuum systems where the of the elastomer could be a significant gas load. A copper ring gasket is used with conflat flanges. The knife edge is recessed in a groove in each flange. The choice of the best system depends on the required standards for example: cost-effectiveness, simple to fit and remove elements, leak tightness, high class materials or the demand for bakeable elements in the ultra high vacuum range.

A vacuum flange is a at the end of a tube used to connect , tubing and to each other. Deformation of the metal gasket fills small defects in the flange. An example of a physical feedthrough is a vacuum-tight connection for cooling water. Some sizes share their flange dimensions with their respective larger neighbor and use the same clamp size. Despite the different naming conventions, the actual flanges are the same. These flanges are elastomeric o-ring seal and can be used for both vacuum and pressure applications. Although these sizes are used in North America, the true nominal bore is often that of standard inch dimensioned tubes.

. For stainless-steel conflat flanges, baking temperatures of 450 °C can be achieved; the temperature is limited by the choice of gasket material. Vacuum flanges are used for scientific and industrial applications to allow various pieces of equipment to interact via physical connections and for vacuum maintenance, monitoring, and manipulation from outside a vacuum's chamber. An extra spring-loaded circular clamp is often used around the large-diameter o-rings to prevent them from rolling off from the centering ring during mounting. Sizes 10, 20 and 32 are less common sizes see. Several flange standards exist with differences in ultimate attainable , size, and ease of attachment. In addition to protecting the knife edge, the groove helps hold the gasket in place, which aligns the two flanges and also reduces gasket expansion during.

Standard sizes are indicated by the nominal inner diameter in millimeters for flanges 10 through 50 mm in diameter. The flange is sized by the largest nominal I. A mechanical feedthrough is used for and of components under vacuum. In North America, flange sizes are given by flange outer diameter in inches, while in Europe and Asia, sizes are given by tube inner diameter in millimeters. Stainless steel is a cleaner, stronger and more durable alternative to aluminium For specific applications, some vacuum components are also available in aluminium. Each flange has a chamfered back-surface and is mated by a circumferential clamp Figure 2 tightened by wing-nut, thumbscrew, bolt, or over-center lever. A wobble stick is a mechanical feedthrough device that can be used to pick up, move and otherwise manipulate objects in the vacuum chamber.
