Product Family ATEX
ATEX standard parts have been developed for explosion hazard conditions in hydraulics or gear construction. Every product includes a documentation showing the underlying European explosion protection directive (ATEX).
Fluid sight glasses EN 543.6 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.
The sight glass is embedded in the body during the injection process and is therefore absolutely leak tight.
The seal is embedded in a radial recess, and thus cannot be squeezed out during tightening.
Assembly note:
For wall thicknesses less than 0.16 in (4 mm), use thin hex nuts GN 7430.
