Polywater | Hauff-Technik sewer pipe mechanical seals keep substances from flowing out of or into critical pipe infrastructure.

Secure, watertight sewer pipe mechanical seals and wall sleeves are of the utmost importance for sewage and water infrastructure. During the transport of sewage or drinking water, reliable mechanical sealing systems need to be installed in order to ensure nothing contaminates drinking water en route to homes, and that wastewater is not leaking on its path to a treatment facility. Polywater | Hauff-Technik has developed sewer pipe mechanical seals, sewer gas leak detectors and other products to offer durable and effective solutions that keep critical public systems up and running. Below are our innovative products that support sewer and water infrastructure — take a look at our offerings or reach out to our team for questions or support.
