|The canister "O" rings were made of natural rubber, white in color, in metric dimensions.
The Type I was 58.5 mm ID with a 3 mm cross section. (blueprint)
The Type II was 71.8 mm ID with a 2.5 mm cross section. (blueprint)
Very close white replacements are available from:
The Type II stock number is WN70146 (measurement of metal canister).
The Type I stock number is WN70228 (per blueprint dimensions).
Neither is metric, but the Type II is within a few tens of thousandths of an inch. The Type I is a bit "fat" in cross section, and a tad "small" in inner diameter.
Both are 70 durometer, a bit harder than the original 55 durometer.
The good news is that these are very inexpensive. The bad news is that they have a minimum order, so you may want to buy a bunch and sell the extras.
Hope this helps someone.
