Description
The York 028-15577-000 O-Ring is a sealing component used in air conditioning units, refrigeration equipment, and heat pump assemblies to prevent leakage at joint connections. It provides a tight seal between metal or polymer mating surfaces to contain refrigerant, oil, or air within the system. It works by compressing within a machined groove, allowing it to deform and fill microscopic gaps when components are tightened. It is fitted at compressor ports, valve housings, and piping connections. In HVAC systems, it supports pressure stability, leak prevention, and operation of cooling and heating circuits.
