2. O-ring - Wikipedia

   en.wikipedia.org/wiki/O-ring

   O-rings are available in various metric and inch standard sizes. Sizes are specified by the inside diameter and the cross section diameter (thickness). In the US the most common standard inch sizes are per SAE AS568C specification (e.g. AS568-214). ISO 3601-1:2012 contains the most commonly used standard sizes, both inch and metric, worldwide.

3. Radial shaft seal - Wikipedia

   en.wikipedia.org/wiki/Radial_shaft_seal

   Depending on the seal type these two angles are varied to create a pressure distribution at the seal contact line which has a steeper slope on the oil side of the seal. The shallower the slope on the oil side of the seal, the wetter the seal will run. The spring is positioned such that axially the centerline of the spring is biased to the air ...

4. O-ring boss seal - Wikipedia

   en.wikipedia.org/wiki/O-ring_boss_seal

   An o-ring boss seal is a technique for joining two fluid-carrying pipes, hoses, or tubing. In an o-ring boss (abbreviated ORB) system, a male-threaded part is inserted into a female-threaded part, providing a mechanical seal. This system differs from others in that a nut is tightened over an o-ring in a chamfered area, creating a fluid-tight ...

5. Seal (mechanical) - Wikipedia

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

   A seal is a device or material that helps join systems, mechanisms or other materials together by preventing leakage (e.g. in a pumping system), containing pressure, or excluding contamination. The effectiveness of a seal is dependent on adhesion in the case of sealants and compression in the case of gaskets .

6. Gasket - Wikipedia

   en.wikipedia.org/wiki/Gasket

   Annular Seal (RTJ Seal) is a high integrity, high temperature, high pressure seal for applications in the oil industry, oilfield drilling, pressure vessel connections, pipes, valves and more. The movement of the ring packing (RTJ) can be described as an irregular flow in the groove of the deformed sealing flange due to the axial compressive load.

7. Hydraulic seal - Wikipedia

   en.wikipedia.org/wiki/Hydraulic_seal

   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
