Gn 744 fluid level sight glasses with prismatic reflector expand the range and usage of oil level sight glasses. With the cats-eye prism effect on the oil color, oil viscosity not-with-standing, the view is quite clear. The real advantage of the prism effect is when over-filling, under-filling and poor lighting situations arise.
- Should not be used in applications where viewing of alcohol level is required
- Fluid level sight glasses can also be used on pressurized tanks
- The o-ring is housed in the same aluminum body as the gn 743 oil level sight glasses
- 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 effected by axial pressures
- The seal is put in a groove in the housing and it can therefore not be lost, in addition, this groove prevents the seal from being extruded when the sight glass is tightened
- The location of the seal also allows the use of a softer elastomer which guarantees better and easier sealing
- Maximum heat resistance: 100°c (212°f)
- When mounting fluid level sight glasses on walls of less than 4mm (.157") thick, use mounting nut part series gn 543.1.
