Glass-Cover up to 12/-1 bar
Product description
Do you need a filling opening or observation glass (if necessary with light and wiper) all hinge-mounted?
Our glass pressure cover was developed especially for this purpose. This cover consists of a flange ring as well as a borosilicate glass-pane conforming to DIN7080. The glass seals directly on the O-ring incorporated into the neck-flange. The viewing aperture is the same as the inner diameter. It is also possible to fasten a light (with folding hinge) to the cover hinge. Moreover it is possible to install a wiper (centered).
