Fluid Level Sight Glasses with Natural Glass
Sealing with an O-ring on the periphery and not on the face edge of the glass, leak tightness is therefore not affected by axial pressures
The seal is housed in a groove and it can therefore not be lost, this groove prevents the seal from being extruded when the sight glass is tightened
NBR seal: maximum heat resistance: 100-Degree C (212-Degree F)
