The robust, scratch-proof glass of the fluid sight glass GN 743.10 is sealed at the edges by an O-ring. The sealing effect is independent of the axial pressure. The sight glasses can also be used in particularly aggressive environments thanks to the materials used.

The outside diameter of the fluid level sight glasses with recessed hex matches the mounting holes for pipe fittings according to DIN 3852.

The outer seal is embedded in a radial recess. In addition, this groove prevents the seal from being ejected when the sight glass is tightened.

Fluid sight glasses GN 743.10 can be used on pressurized tanks. Tests regarding maximum pressure are available.
