4" Sight Tower B-Quality

Sight tower with ends made of stainless steel and cylinder made of borosilicate glass in 4 inch, which is compatible with all of our products with 4 inch tri-clamp flange connection.

This high quality inline sight glass is the base for our extremely popular Crystal Dragon, a glass column, which allows a free 360° view at the events on the inside. It is also suitable for many other applications, such as a hop infuser, yeast harvester or filter assembly.

Please be aware that although borosilicate glass is very robust, it can have asperities and air entrapment in the glass, as well as asperities by chipping at the edges due to the difficult processing. This is not a product flaw, but a characteristic caused by production. Please handle items made of borosilicate glass with utmost care, do not clamp them too tight, and do not put them down onto hard surfaces! All glasses are carefully inspected by us before delivery and singled out if deviant. We can not accept subsequent complaints.

B-Quality: The sight tower is not compatible with our 4" Crystal Dragon glass cylinder.

However, it is well made and has no other flaws.
