[SML] Littlite o-ring size?

[Duncan Mahoney]

There are plenty of O-ring size charts online.   If you can estimate the ID or OD and cross section of the O-ring, you can find the size number.  Vendors like McMaster-Carr have O-rings in different materials that will be more heat resistant (and more expensive) than plain old rubber, but by the bag of 100, plain old rubber O-rings are pretty cheap
