Product description
Oil sight glasses GN 743.5 offer genuine glass of high stability and scratch proof. The seal 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 outside diameter of these oil sight glasses with recessed hexagon is chosen to match mounting holes for tube connections according to DIN 3852.
The sealing ring is housed in a groove and it can therefore not be lost. In addition, this groove prevents the seal from being extruded when the sight glass is tightened.
Oil sight glasses GN 743.5 can also be used on pressurised tanks. Tests regarding maximum pressure are available.
Assembly instruction:
For mounting on walls of less than 4 mm thickness please use a mounting nuts GN 7430.
