Sorry to burst your bubble, but Googe was asking about the glasses, which are larger than the diameter of pipe for which they are used. I can't measure them at the moment, sorry Googe. If no one gets to it first, I'll measure them tonight.
If a 3" sight glass only had a diameter of 3", it would only be applying a seal along the 1.6mm odd pipe thickness...however they cover from the pipe out to the edge of the ferrule :handgestures-thumbupleft:
edit: I see you identified this issue :p I'll measure some later tonight and post.
