• Loss of cabin cooling from worn sealing surfaces
• Service leaks after compressor, condenser, or line replacement
• Seal deterioration caused by age, heat, and system exposure

Installation Notes

Inspect the mating surfaces, clean the connection points, and verify the correct seal size before assembly. Use proper A/C service procedures, evacuate and recharge the system after repair, and confirm there are no leaks at the serviced joints. RS2631 is listed for N/A position applications, so fitment should be verified by model and year.
