With Screw-Together Window (Unassembled)
Weld these sights to single-wall tanks. They’re often used to monitor contents in process vessels, mixers, and bulk containers.
316L stainless steel sights are more corrosion resistant than 304 stainless steel sights.
DIN 11851 rated sights meet dairy fitting standards.
Sights with a bolt-on window should be welded to a hole in your tank wall.
Sights with a screw-together window make it easier to access your tank and clean the window than sights with a bolt-on window. To install these sights, place the body in a hole on your tank wall and weld it. Then twist on the window and tighten with a spanner wrench.
