PVC fittings are the recommended choice for air conditioning condensate disposal due to their resistance to corrosion and ability to handle the acidic nature of condensate water. Condensate lines, which carry water that accumulates from the cooling process of air conditioning systems, can produce moisture that is often slightly acidic, especially in systems that operate with certain refrigerants.

Using PVC fittings ensures durability and a long lifespan for the plumbing system since PVC does not rust or corrode like metals. Furthermore, PVC is lightweight and easy to work with, making installation and modifications simpler for plumbers. Additionally, it is important to note that PVC fittings meet building codes and standards for condensate disposal, ensuring compliance with local regulations.

Other fitting types, while they have their uses in various plumbing applications, may not provide the same level of protection against corrosion and may not be as suitable for handling the specific requirements of air conditioning condensate disposal.
