The gap between the flange faces has been exaggerated by a factor of four to make it clearly visible. The choke flange can also be mated with a plain cover flange and still form a pressure seal. A choke connection is formed by mating one choke flange and one cover (or gasket/cover) flange. The central region of the choke flange face is very ...
In mechanical engineering, a face seal is a seal in which the sealing surfaces are normal to the axis of the seal. Face seals are typically used in static applications and are used to prevent leakage in the radial direction with respect to the axis of the seal. [1] Face seals are often located in a groove or cavity on a flange. Face seals are a ...
Because the ring is subject to the ambient pressure and the partial pressure of gases only at the seal, their gradients will be steep near the seal and shallow in the bulk (opposite to the gradient of the contact stress [15] (See Vacuum flange#KF.2FQF.) High-vacuum systems below 10 −9 Torr use copper or nickel O-rings.
In mechanical engineering, an end-face mechanical seal (often shortened to mechanical seal) is a type of seal used in rotating equipment, such as pumps, mixers, blowers, and compressors. When a pump operates, the liquid could leak out of the pump between the rotating shaft and the stationary pump casing. Since the shaft rotates, preventing this ...
Cryogenic seals provide a mechanical containment mechanism for materials held at cryogenic temperatures, such as cryogenic fluids. Various techniques, including soldering and welding are available for creating seals; however, specialized materials and processes are necessary to hermetically entrap cryogenic constituents under vacuum-tight conditions.

A vacuum flange is a flange at the end of a tube used to connect vacuum chambers, tubing and vacuum pumps to each other. 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.
Amazon — Husbands and kids can buy typical Mother's Day gifts (e.g. bed and bath items, a new washing machine) on the website… but moms use it to buy vibrating massagers (which one daughter mistakes for a microphone) or the best-selling novel Fifty Shades of Grey (in hard-copy or, so the husband doesn't have to know she's reading it, on ...
