2. Gasket - Wikipedia

   en.wikipedia.org/wiki/Gasket

   Sheet gaskets; Corrugated metal gaskets; Ring gaskets; Spiral wound gaskets; Sheet gaskets are simple, they are cut to size either with bolt holes or without holes for standard sizes with various thickness and material suitable to media and temperature pressure of pipeline. Ring gaskets also known as RTJ.

3. Compression seal fitting - Wikipedia

   en.wikipedia.org/wiki/Compression_seal_fitting

   A compression seal fitting, unlike an epoxy seal or gasket, uses mechanical components and an axial force to compress a soft sealant inside a body which then creates a seal. An epoxy seal differs in that it is composed of some type of compound which is poured into a mold in an attempt to create a seal.

4. Piping and plumbing fitting - Wikipedia

   Gaskets are mechanical seals, usually ring-shaped, which seal flange joints. [3] Gaskets vary by construction, materials and features. Commonly used gaskets are non-metallic (ASME B 16.21), spiral-wound (ASME B 16.20) and ring-joint (ASME B 16.20). Non-metallic gaskets are used with flat- or raised-face flanges.

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. Bonded seal - Wikipedia

   en.wikipedia.org/wiki/Bonded_seal

   It is the compression of the elastomeric part between the faces of the parts on either side of the bonded seal that provides the sealing action. The elastomeric material, typically nitrile rubber, is bonded by heat and pressure to the outer ring, which holds it in place. This structure increases resistance to bursting, increasing the pressure ...

7. Glass-to-metal seal - Wikipedia

   en.wikipedia.org/wiki/Glass-to-metal_seal

   Glass-to-metal seals are a type of mechanical seal which joins glass and metal surfaces. They are very important elements in the construction of vacuum tubes , electric discharge tubes , incandescent light bulbs , glass-encapsulated semiconductor diodes , reed switches , glass windows in metal cases, and metal or ceramic packages of electronic ...
