Product Details
The Fluid Level Sight Glass GN 743.2 features genuine natural glass that offers high stability and scratch resistance, with a sealing O-ring located on the periphery rather than the face edge, ensuring leak tightness is unaffected by axial pressures. The outside diameter is designed to match mounting holes for tube fittings in accordance with DIN 3865, and the seal is securely housed in a groove that prevents loss or extrusion during tightening, while also allowing for the use of a softer elastomer for improved sealing. This model is compatible with pressurized oil tanks and suitable for applications involving subpressure, with a maximum heat resistance of 100°C (212°F). For installations on walls less than 4mm thick, nut GN 543.1 should be utilized.
