Product Details
The GN 537 fluid level sight glasses are designed for easy installation without the need for threading, as they are inserted into the bore D2, tolerance H11. The assembly process involves tightening the ring nut with a pin key, which simultaneously presses the seal against the contact surface to secure the sight glass in position. For removal, the procedure is simply reversed. These sight glasses are suitable for applications in non-pressurized or slightly pressurized tanks and can withstand a maximum heat resistance of 80° C (175° F).
