Fluid sight glasses GN 743.6 are suitable for use in potentially explosive atmospheres. They comply with the European explosion protection directive (ATEX) 2014/34/EU.
A detailed operating instruction is available and included with every fluid sight glass. In addition, the housings are provided with an ATEX label.
These fluid sight glasses offer a scratch proof sight glass of high stability. The placement of the seal on the outer diameter of the glass eliminates leakage independent from over or under tightening of the sight glass.
The seal is embedded in a radial recess, and thus cannot be lost or squeezed out during tightening.
These fluid sight glasses can also be used on pressurized tanks. Tests regarding maximum pressure are available.
Assembly note:
For wall thicknesses below 0.16 in (4 mm), use GN 7430 thin hex nuts.
