York 026-37571-000 GAGE LIQUID LEVEL SIGHT FRONT Sight Glass

026-37571-000 is a YORK original liquid level sight glass (Sight Glass / Gage Liquid Level), produced by Johnson Controls. It is of the front-mounted (Front) structure and is used for direct observation of the refrigerant level in the York chiller. This sight glass is installed at the front end of the evaporator or condenser cylinder of the unit. Through a high-strength transparent window, it visually displays the level of the refrigerant inside, facilitating the quick judgment by maintenance personnel on whether the refrigerant charging quantity is appropriate, whether there is a shortage of refrigerant or an excess. At the same time, it can be combined with the humidity indication function. By observing the color change, the moisture content in the system can be determined, and leaks or drying failure can be detected in time. The sight glass adopts a pressure-resistant glass and metal shell sealing structure. The sealing performance is reliable and it can withstand the erosion of refrigerating oil and refrigerant for a long time, without leakage or fogging.
