2. Seal (mechanical) - Wikipedia

   en.wikipedia.org/wiki/Seal_(mechanical)

   Seal types: Induction sealing or cap sealing; Adhesive, sealant; Bodok seal, a specialized gas sealing washer for medical applications; Bonded seal, also known as Dowty seal or Dowty washer. A type of washer with integral gasket, widely used to provide a seal at the entry point of a screw or bolt [2] [3]

3. API Standard 682 - Wikipedia

   en.wikipedia.org/wiki/API_Standard_682

   Three new seal types were introduced in the 2nd Edition: dry running containment seals, non-contacting seals, and dual gas barrier seals. [4] Containment seals are the outer seal of Arrangement 2. In the 2nd Edition, containment seals can be used with a liquid buffer fluid, a gas buffer fluid or without a buffer fluid.

4. Gasket - Wikipedia

   en.wikipedia.org/wiki/Gasket

   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.

5. O-ring - Wikipedia

   en.wikipedia.org/wiki/O-ring

   Typical O-ring and application. An O-ring, also known as a packing or a toric joint, is a mechanical gasket in the shape of a torus; it is a loop of elastomer with a round cross-section, designed to be seated in a groove and compressed during assembly between two or more parts, forming a seal at the interface.

6. Hydraulic seal - Wikipedia

   en.wikipedia.org/wiki/Hydraulic_seal

   Hydraulic seals are classified based on their function and working conditions: Static. 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.

7. Piping and plumbing fitting - Wikipedia

   en.wikipedia.org/wiki/Piping_and_plumbing_fitting

   Non-metallic gaskets are used with flat- or raised-face flanges. Spiral-wound gaskets are used with raised-face flanges, and ring-joint gaskets are used with ring-type joint (RTJ) flanges. Stress develops between an RTJ gasket and the flange groove when the gasket is bolted to a flange, leading to plastic deformation of the gasket. [4]

8. End-face mechanical seal - Wikipedia

   en.wikipedia.org/wiki/End-face_mechanical_seal

   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 ...

9. Dry gas seal - Wikipedia

   en.wikipedia.org/wiki/Dry_gas_seal

   Dry gas seals are non-contacting, dry-running mechanical face seals that consist of a mating (rotating) ring and a primary (stationary) ring. When operating, lifting geometry in the rotating ring generates a fluid-dynamic lifting force causing the stationary ring to separate and create a gap between the two rings.
