Product description

Information

Fluid sight glasses EN 541.6 are suitable for use in potentially explosive atmospheres. They comply with the European explosion protection directive (ATEX) 2014/34/EU.

A detailed operating instruction is available and included with every fluid sight glass.

These fluid sight glasses made of polyamide plastic have a high mechanical strength. Therefore, they can be produced with thinner walls with a large viewing window.

Assembly note:
For wall thicknesses below 0.16 in (4 mm), use thin hex nuts GN 7430.
