    I can find several web sources for new 1100 o-rings, but it seems to be a guarded secret as to what the actual size is supposed to be. I guess that is the only way they can get a buck or two for them. I just happen to work where quality o-rings are plentiful and cheap. They won't cost me anything if I know the correct size to use.

    I took the new gas system oring off my Remington 1100 shotgun to work today. I used our o-ring measuring devices and came up with this...

    The O-ring was measured out to be a size 0-22 with a durometer of 70-75. I am guessing the material to be Buna or Viton. Does anyone have any information to verify or disprove this information?

    You seem to have a bit of knowledge as to the size and type of gas seal O-ring. I have owned and shot 1100's for years, and still do. I have shot thousands of rounds and have only had two wearout or break.
    All I have to do is call Remington, pay $7 and get a replacement guaranteed right size and spec material. Why pinch pennies? How many do you plan on wearing out?
