Flexseal Drain Couplings, also known as couplers, are straightforward and user-friendly connectors for drainage pipes. They are engineered to join two pipes that have identical or similar outer diameters. Constructed from EPDM Rubber compliant with BS EN686 and featuring Stainless Steel grade 309, these couplings offer a swift and effective solution for connecting pipes made from different materials but sharing comparable outer diameters. These are reliable, proven products available in a wide array of sizes to suit numerous pipe configurations. Fernco Drain Couplings are designed to connect pipes with the same or similar outside diameters and can be secured using a nut driver and torque wrench, forming a lasting airtight and watertight seal instantly. Each coupling consists of a molded EPDM rubber body and two stainless steel clamp bands. Applications include housing sites, private roads, industrial sites, and agricultural land, as well as for repairing existing pipe systems by replacing short pipe sections. They are an economical choice for unadopted (private) drainage pipes and can connect plain-ended pipes, ensuring a completely airtight and watertight connection. They are simple, versatile, and easy to fit.
