YORK 026-46487-000 Sight Glass

YORK 026-46487-000 is the refrigerant sight glass provided by the original factory for York refrigeration units. It is specifically designed for York screw-type water chillers and their associated refrigeration piping systems. It is the core component for visual monitoring of the status of the refrigeration system.

This sight glass features a high-strength tempered glass window combined with a corrosion-resistant metal valve body. It has excellent sealing performance and can withstand the high-pressure conditions of the refrigeration system. It can resist the long-term erosion of common refrigerants such as R134a and refrigerating oils, and is not prone to leakage or fogging. Its main function is to be installed in the refrigeration piping system, allowing for direct observation of the flow state and liquid level height of the refrigerant. By observing the number of bubbles in the piping, it can determine whether the refrigerant charging is sufficient. At the same time, it can identify whether impurities or moisture are mixed in the refrigerant and assist in determining whether there are risks of dirt blockage or ice blockage in the system.

The standard installation position is at the outlet of the storage tank and the liquid pipe at the front end of the expansion valve. Without the need to disassemble the machine, it can quickly complete the system status inspection, significantly improving the efficiency of refrigerant charging and debugging, daily inspection, and fault diagnosis. As an original factory specification spare part, its interface size and installation position are fully compatible with the corresponding models of York, and it can be directly replaced in situ. It is a commonly used replacement part for refrigeration system maintenance.
