Pyrex® Brand 7740 3/4" Annular Edge
glass is no longer produced by Corning manufacturing company due
to the shutdown of the Sunderland, England manufacturing plant.
This announcement was made by Corning and anticipates not being
able to produce Pyrex® Rolled Sheet, Pyrex® Sight Glass,
reflectors or lens covers.
The only replacement for Pyrex®
brand Annular edge sight glass is the
Maxos® annular edge replacement
circles. The Maxos®
sight glass is molded for formulated borosilicate 8488 glass
which in comparison gives a superior quality of cut and ground
glass. Maxos® also has a 3/4" uniform thickness throughout
as compared to the 5/8" minimum thickness of Pyrex® annular
edge. The extra thickness gives boiler operators extra
safety for their application.
