PVC male adaptor is a pipe fitting with one plain, solvent-weldable end for connecting to a PVC pipe and one externally threaded end for connecting to a female-threaded fixture or valve. Its purpose is to provide a strong, leak-proof transition from a plain PVC pipe system to a threaded connection, making it essential for plumbing, irrigation, and various industrial fluid systems that require the integration of threaded components like pumps, valves, or other accessories.
