Product Details
The GN 537 fluid level sight glasses are designed for easy installation without the need for threading, as they fit into a bore D2 with a tolerance of H11. Installation is accomplished by inserting the sight glass and tightening the ring nut with a pin key, which presses the seal against the contact surface to securely hold the sight glass in place. To remove, the process is simply reversed. This product is suitable for non-pressurized or slightly pressurized tanks, featuring a maximum heat resistance of 80° C (175° F).
