Product description


EN 541.2 Elesa® original design technopolymer plastic fluid level sight glasses.

These crystal-clear oil level sight glasses are fitted with a window creating the prismatic effect of a "cat’s eye" to provide a clear oil level reading regardless of oil color or viscosity. The advantage of this is obvious in cases such as underfilling or overfilling, or monitoring the level under unfavorable conditions.

Resistant to solvents, oils, grease and other chemical agents.

EN 541.2 Fluid level sight glass can also be used in tanks which are pressurized. Test results are available.

Assembly instruction:
For mounting on walls of less than 4 mm thickness please use a GN 543.1 nut.
