A Trane RNG02114 O-Ring seals refrigerant connections to preserve pressure balance and steady performance within the heating and cooling unit.
The o-ring forms a barrier at refrigerant connections to maintain proper system pressure and prevent leaks during operation. Its specific inside diameter and cross-section are critical for matching the sealing surface correctly, which supports reliable performance in a heating and cooling system under refrigerant exposure.
The o-ring might need replacement if the HVAC system shows refrigerant loss, reduced cooling capacity, pressure instability or inefficient operation. Common indicators include visible cracking, flattening, swelling or hardening and you might notice oily residue around fittings or signs of wear after prolonged exposure to refrigerant and temperature changes.
