PPH Coupling

Straight Connector for PPH Pipe Extensions

This is a basic fitting for straight-line connections of same-diameter PPH pipes. It is also called a PPH straight coupling or PPH pipe socket. It has sockets on both ends. You insert the ends of two pipes into each end. Socket fusion creates a strong, leak-free joint. The connection becomes as strong as the pipe itself. This is one of the most commonly used fittings in PPH piping installation. You will use it in chemical high-temperature pipelines, industrial wastewater systems, semiconductor ultra-pure water lines, and straight connection sections of various PPH piping projects. The fitting inherits PPH's heat resistance up to 100°C.

Our predecessor company set up overseas plastic mold R&D centers starting in 2017. We gained deep knowledge of PPH material processing and connection technology. In 2022, we built our production base in Huoshan and put this knowledge into practice. Our PPH couplings have accurate dimensions. The socket fits the pipe properly. We hold ISO9001, ISO14001, and ISO45001 certifications. Products come with complete test reports and certificates. We provide free samples for testing before you place a bulk order.
