Fluid sight glasses GN 744 in type A use the prismatic effect of a cat’s eye to give a clear indication of the fluid level unaffected by fluid color or fluid viscosity. The advantage of this effect is particularly obvious in the case of underfilling or overfilling and for inspection under unfavorable light conditions.
The seal is embedded in a radial recess, and thus cannot be lost or squeezed out during tightening.
These fluid sight glasses can also be used on pressurized tanks. Tests regarding maximum pressure are available.
For wall thicknesses below 4 mm, use thin hex nuts GN 7430.
Aluminum, fine turned
Crystal clear Polyamide PA-T
Temperature resistant up to 230 °F (110 °C)
