What are air conditioner o rings?

Air conditioner O-rings are small, circular seals made of rubber or other materials used to create a tight seal between different components in an AC system, such as between hoses, fittings, and compressors. They help prevent refrigerant leaks, ensuring the efficient operation of the air conditioning system. Properly functioning O-rings are essential for maintaining optimal pressure and performance, as well as preventing damage to the system. Regular inspection and replacement of worn O-rings can help prolong the life of the AC unit.
