Yes, plastic pipe fittings can be resistant to ultraviolet degradation. Many plastic materials used in pipe fittings, such as PVC (polyvinyl chloride) and CPVC (chlorinated polyvinyl chloride), are formulated to have UV stabilizers that protect against the harmful effects of ultraviolet radiation, making them suitable for outdoor applications. However, the degree of UV resistance can vary depending on the specific material and its formulation, so it is important to choose fittings specifically designed for UV exposure if required.
