Designed for demanding civil engineering, groundwork, and utility applications, this 150mm steel pipe stopper offers a robust mechanical solution for isolating or pressure-testing pipelines. The durable construction features dual steel plates treated with a corrosion-resistant finish, ensuring reliable service in wet, abrasive, and chemically aggressive pipe environments. Operation is straightforward and efficient. Turning the central wing nut compresses the high-grade rubber ring, expanding it firmly against the internal pipe wall to create a tight, leak-proof seal. The stopper includes a threaded central bypass nipple, allowing engineers to vent air, run water tests, or attach bypass hoses safely while maintaining full control over the pipe network flow.
