Fluid sight glasses EN 541.3 made of polyamide plastic have a high mechanical strength. Therefore, they can be produced with thinner walls.
These fluid sight glasses 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.
These fluid sight glasses can also be used on pressurized tanks. Tests regarding maximum pressure are available.
Assembly note:
For wall thicknesses below 0.16 in (4 mm), use thin hex nuts GN 7430.
