EN 546.1 Dome-Shaped Plastic Fluid Level Sight Glasses Technopolymer Plastic, with Marking Ring


ELESA original design
code: HCFE

Product description


EN 546 dome-shaped fluid level sight glasses mainly used as fluid circulation indicators.

Because of the high strength of the technopolymer plastic fluid level sight glasses, these site glasses can be produced with much thinner walls, resulting in clearer visibility. The ration between bore diameter and the viewing window is much imrpoved.

Assembly instruction:
For mounting on walls of less than 4 mm thickness please use a GN 7430 mounting nuts.
