And as we know Orings (and all other seals) work by creating positive pressure against a surface thereby preventing leaks and This was famously demonstrated physics professor Richard Feynman, when he placed a small Oring into icecold water, and subsequently showed its loss of flexibility before an investigative committee that this was the caused that at crucial need the Oring couldChallenger on the launchpad Arrow indicating leaking Oring on SRB After the space shuttle Challenger and its crew were destroyed in a fiery, catastrophic explosion on , NASA appointed members of the Rogers Commission to investigate the cause of the disasterAladdin PacFab Challenger Repair Kit Seal, Diffuser ORing, Housing ORing, Strainer ORing, Lid ORings, are some toolkits used for the pool maintenance They are made of metal so that it can deform and tightly fill the space for any slight irregularities They are inexpensive, easy to make, reliable and are simple framing requirements

Answer (1 of 12) Like with most things that are risky, redundancy is a very good thing Such was the case with many if not most of the Space Shuttle Systems, and the Solid Rocket Boosters were no different The ORings were simply put seals betweenAs most of us know, Challenger is the name for one of NASA's space shuttle orbiters that experienced a catastrophic failure on resulting in the death of all seven on board 5 astronauts, and 2 payload specialists It was determined that the catastrophic failure resulted after all five Oring seals in its right solid rocketThe gas pressure formed by combustion inside the SRB also helps to seal the O ring This process of sealing is called Pressure Actuation Of ORing Seal As the gas goes toward the Oring, gas meets one side of the Oring and pushes the Oring from all the sides possible into the gap, thus helping to seal the joint
The Challenger was lost because one small part an Oring seal failed during a launch in cold weather The possibility of this part failing had been predicted long before, butOn Jan 16 and 17 of this year, less than two weeks before the Challenger disaster, NASA engineers and those from Thiokol met at Marshall toThe Presidential Commission's inquiry concluded the cause of the Challenger accident was the failure of the pressure seal in the aft field joint of the Solid Rocket Motor In fact, the aft field joint had two O‑ring seals, a primary seal and a secondary seal as a backup, therefore both seals must have failed and the Pres Comm's report should have read the failure of both pressure seals
In the Parker ORing Handbook ORD 5700 paragraph 40 says It has been said that Orings are 'the finest static seals ever developed' Perhaps the prime reason for this is because they are almost human proof If the gland has been designed and machined properly The disaster of Challenger mission STS51L was the result of human engineeringTheir investigation revealed that the Oring seal on Challenger's solid rocket booster, which had become brittle in the cold temperatures, failed Flames thenCrosman Benjamin Bulldog 357 Air Rifle 2x COLOR CODED ORing Kit $1275 $1275 Crosman Benjamin Discovery BP1K77 (177) &
