2. O-ring - Wikipedia

   en.wikipedia.org/wiki/O-ring

   The wide range of potential liquids and gases that need to be sealed has necessitated the development of a wide range of O-ring materials. [2] O-rings are one of the most common seals used in machine design because they are inexpensive, easy to make, reliable and have simple mounting requirements.

3. FFKM - Wikipedia

   en.wikipedia.org/wiki/FFKM

   Certain grades have a maximum continuous service temperature of 327 °C (621 °F). They are commonly used to make O-rings and gaskets that are used in applications that involve contact with hydrocarbons or highly corrosive fluids, or when a wide range of temperatures is encountered.

   Silicone greases generally have an operating temperature range of approximately −40 to 200 °C (−40 to 392 °F) ... 'O' rings and couplings.

5. Cryogenic seal - Wikipedia

   en.wikipedia.org/wiki/Cryogenic_seal

   Pure indium wire or solder preform washers are accepted as the most reliable low temperature sealing materials. When correctly formed, indium will afford leak rates of less than 4.0x10 -9 mbar- liter/sec. [ 2 ] Alternative cryogenic seal materials include silicone grease conical seals, and Pb/Sn (lead-tin) wire seals.

6. Space Shuttle Challenger disaster - Wikipedia

   en.wikipedia.org/wiki/Space_Shuttle_Challenger...

   The amount of O-ring erosion was insufficient to prevent the O-ring from sealing, and investigators concluded that the soot between the O-rings resulted from non-uniform pressure at the time of ignition. [3]: 130 [6]: 39–42 The January 1985 launch of STS-51-C was the coldest Space Shuttle launch to date. The air temperature was 62 °F (17 °C ...

8. Wills Ring - Wikipedia

   en.wikipedia.org/wiki/Wills_Ring

   A Wills Ring is an O-ring in the form of a hollow metallic tube. They are pressurised internally by gas pressure [1] The advantages of this construction are that the rings can seal against a wide range of conditions. [2] Metallic construction makes them robust against high or low temperatures and chemical attack.
