Trane RNG1764 O-Ring 0.924" X 0.116"

The Trane RNG1764 is a seemingly inconsequential yet a critically necessary part for your Trane HVAC system – an O-ring. This is a donut-shaped ring with a length of 4” and an inner diameter of 0.924” and outer diameter of 0.116” made of elastomeric material; it is crucial for sealing and preventing leaks within your Trane system. This also provides protection against refrigerant leakage by establishing a close fit between mating surfaces. Leakage can severely affect the functionality and productivity of your system and in the worst-case scenario, it releases toxic refrigerant gases into your home. Trane O-rings are located in many areas of your Trane HVAC system to guarantee its correct operation and optimum performance.
