The Trane RNG14103 O-Ring is an OEM sealing component for compatible Trane HVAC and refrigeration equipment. The part is identified with an approximate 0.859-inch inside diameter and 0.139-inch radial cross section.
This Trane O-ring seal is used where the RNG14103 part number is specified to maintain proper sealing between mating components. Correct O-ring sizing is important in HVACR applications because an incorrect inside diameter or cross section can result in improper compression, refrigerant or oil leakage, and premature seal failure.
Before installation, technicians should inspect the O-ring groove and mating surfaces for contamination, scratches, corrosion, or other damage. The seal material and any lubricant used must also be suitable for the refrigerant, oil, operating temperature, and pressure of the specific system.
Always verify RNG14103 against the complete Trane equipment model, serial number, and assembly before ordering.

Common Questions
What size is the Trane RNG14103 O-ring? The listed dimensions are approximately 0.859-inch ID × 0.139-inch cross section.
Is RNG14103 equivalent to an AS568-212 O-ring? The dimensions closely correspond to AS568-212 sizing. However, dimensional similarity alone does not confirm that a generic O-ring is a suitable replacement.
Can I substitute a generic O-ring with the same dimensions? Not automatically. The elastomer material, hardness, refrigerant compatibility, oil compatibility, temperature range, and pressure requirements must also be correct for the application.
How do I confirm RNG14103 fits my Trane equipment? Verify the complete equipment model and serial number, assembly location, and original part number before ordering. Do not select a replacement based solely on dimensions.
