Product Description

GN743.6 ATEX Sight Glass, for Use in Explosion Risk Areas

The European guidelines for explosion protection introduced on 1st July 2003 (ATEX) also cover the explosion protection in the mechanical sector.

Level sight glasses GN 743.6 are suitable for use in an explosion risk environment. They comply with the guidelines 94/9/EG. Detailed documentation is available and forms part of an order for this product.

Further salient points of the oil level sight glasses GN743.6 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. For this reason the seal has been made of relatively soft material which improves the sealing capability even on a slightly imperfect contact surface.
