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 with a tolerance of H11. The installation process is straightforward; by tightening the ring nut using a pin key, the seal is compressed against the contact surface, securely holding the sight glass in position. For removal, the procedure can be reversed. These sight glasses are suitable for use in non-pressurized or slightly pressurized tanks, featuring a maximum heat resistance of 80° C (175° F).
