EN 543.2 Fluid Sight Glasses Plastic

Original design
code: HGFT.

Type: A - With reflector
Color: RT - Red, shiny finish

Plastic Characteristics

Product description

The sight glass of fluid sight glasses EN 543.2 is molded 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.

The red version indicates a "control point".

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