Inflatable seals can be used for numerous applications with difficult sealing issues. Labyrinth seal A seal which creates a tortuous path for the liquid to flow through; Lid (container) Rotating face mechanical seal; Face seal; Plug; Radial shaft seal; Trap (plumbing) (siphon trap) Stuffing box (mechanical packing) Wiper seal; Dry gas seal
A gasket is a mechanical seal which fills the space between two or more mating surfaces, generally to prevent leakage from or into the joined objects while under compression. It is a deformable material that is used to create a static seal and maintain that seal under various operating conditions in a mechanical assembly. [1]
Once pressure is applied and the seal comes together, a viscous liquid is released between the two seal faces and a thin film is formed to help create an airtight seal. If the amount of pressure inside of the seal is increased and there is an excess of pressure between the face plates, the two faces move apart and the seal begins to open.
Meter seals are used with electric or gas or water meters and usually molded in polycarbonate. The transparent body of the seal means that the locking mechanism is visible, and can provide clear indication of tampering. Meter seals can withstand exposure to sunlight and extreme weather, and a wide range of temperatures.
Clean, oxide-free indium will cold weld to itself. The mating ends of a wire seal will weld together under compression. [12] A more reliable alternative to a seal made from indium wire is a seal that uses an indium washer. Washers minimize the risk of seal degradation and cryogenic leaks by eliminating the interface between connected butt ends ...
A static hydraulic seal is located in a groove and sees no movement - only sealing within its confined space, acting like a gasket. To achieve this the gasket should be under pressure. The pressure is applied by tightening of the bolts. Examples of static seals include O-rings, flange seals, and cover seals. Dynamic
