Product description

ATEX-Sight glasses GN 543.6 are suitable for use in an explosion risk environment. They comply with the guidelines (ATEX) 2014/34/EU.

A detailed operating instruction is available and included with every sight glass.

The window is embedded in the body during the injection process and it is therefore absolutely leaktight.

The sealing ring is embedded in a radial undercut and it cannot be extruded during the tightening operation.

Assembly instruction:
For mounting on walls of less than 4 mm thickness please use mounting nuts GN 7430.
