Fluid Sight Glasses GN 743.3

Product description

Information

Fluid sight glasses GN 743.3 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 outer diameter of these fluid sight glasses with recessed hex is matched to screw-in holes for pipe fittings according to DIN 3852.

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.
