Trane RNG2119 O-Ring Refrigerant Only 24.94 X 2.75

The Trane RNG2119 is a direct specific type replacement part for Trane HVAC systems that employs the use of refrigerants. An O-ring is a gasket with the outside circular cross-section, and its total length is 12 inches. In its application, it plays the role of a seal at refrigerant connections to prevent any leakage. Think about a round doughnut like structure with two connected parts. It has an inner diameter of approximately 24.94”, 25” in fraction, and an exterior diameter of 0.275”. It is thus possible to obtain a leak-proof seal since the two parts fit the other perfectly in terms of the intended shapes of the two surfaces to be joined.
