Description
The Trane RNG02116 Refrigerant O-Ring 21.955″ ID X 0.275″ RD is a sealing component used to prevent RF leakage at mating connections within HVAC systems and refrigeration equipment. Sized with an inside diameter and profile, it creates a tight seal between joined parts exposed to refrigerant pressure and temperature variation. This is commonly applied in chillers, rooftop units, condensers, and other refrigerant-based systems where secure containment is necessary for proper operation. Within the refrigeration circuit, it maintains system integrity, supports pressure retention, and reduces the risk of refrigerant loss during equipment operation or servicing.
