HDPE Male Threaded Adapter
An HDPE Male Threaded Adapter is a pipe fitting made from high-density polyethylene (PE80/PE100 grades), designed to connect an HDPE pipe to a female-threaded component such as valves, pumps, or metal fittings. It ensures a strong, leak-proof, and corrosion-resistant transition between HDPE piping and threaded systems, making it highly reliable for sewage, gas distribution, and industrial applications with a long service life.
