2. Gasket - Wikipedia

   en.wikipedia.org/wiki/Gasket

   Some seals and gaskets. 1. o-ring. 2. fiber washer. 3. paper gasket. 4. cylinder head 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 ...

3. O-ring - Wikipedia

   en.wikipedia.org/wiki/O-ring

   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. The O-ring may be used in static applications or in dynamic ...

4. Head gasket - Wikipedia

   en.wikipedia.org/wiki/Head_gasket

   Head gasket (in dark gray with a red border) sitting on top of an inline-four engine block. When installed, the four large holes will align with the cylinders. In an internal combustion engine, a head gasket provides the seal between the engine block and cylinder head (s). Its purpose is to seal the combustion gases within the cylinders and to ...

5. Silicone - Wikipedia

   en.wikipedia.org/wiki/Silicone

   Silicone caulk can be used as a basic sealant against water and air penetration. In organosilicon and polymer chemistry, a silicone or polysiloxane is a polymer composed of repeating units of siloxane (−O−R 2 Si−O−SiR 2 −, where R = organic group). They are typically colorless oils or rubber-like substances. Silicones are used in ...

6. RTV silicone - Wikipedia

   en.wikipedia.org/wiki/RTV_silicone

   RTV silicones are made from a mixtures of silicone polymers, fillers, and organoreactive silane catalysts. Silicones are formed from a Si–O bond, but can have a wide variety of side chains. [ 3] The silicone polymers are often made by reacting dimethyl dichlorosilane with water. [ 4] Linear dimethylpolysiloxane polymer reaction.

7. Compression seal fitting - Wikipedia

   en.wikipedia.org/wiki/Compression_seal_fitting

   Compression seal fitting. In mechanical engineering, a compression seal fitting, also known as a sealing gland, is intended to seal some type of element ( probe, wire, conductor, pipe, tube, fiber-optic cable, etc.) when the element must pass through a pressure or environmental boundary. [1] A compression seal fitting may serve several purposes:
