Replacement Glass Cylinder For Tri Clamp In-Line Sight Glass

The borosilicate sight glass cylinders are used in our standard length tri clamp in-line sight glasses, it's also the same as the ones on the 2"-8" glass reflux columns and sight glass with bubble plate, if you are looking for tall or shorter sight glasses, please send us a message.   The size stands for the tri clamp size of the sight glass, for example if you have a 3" tri clamp sight glass from us when ordering the replacement you can just go by the sight glass size and order the 3", please note that there may be minor errors in the diameter of the glasses between different batches but it makes no difference.
