ATEX-Sight glasses GN 743.6 are suitable for use in an explosion risk environment. They comply with the guidelines 2014/34/EU. Detailed documentation is available and forms part of an order for this product.

A detailed operating instruction is included.

In addition, the body is provided with an ATEX-label.

Further salient points of the oil level sight glasses GN 743.6 are:

Genuine glass of high stability and scratch proof. The sealing is achieved with an O-ring on the periphery and not on the face edge of the glass. Leak tightness is therefore not affected by axial pressures.

The sealing ring is embedded in a radial groove and cannot drop out, nor can it be extruded when tightening torque is applied.

Sight glasses GN 743.6 can be used on pressurised oil tanks. Tests regarding maximum pressure are available on request.

Assembly instruction:
