Floplast Flexible Coupling (98-115mm)

The 110mm Flexible Drain Coupling (often referred to as a Fernco or Flexseal coupling) is the ultimate solution for emergency repairs and tricky pipe connections. Unlike rigid uPVC fittings, this flexible coupler is made from heavy-duty, elastomeric EPDM rubber, allowing it to absorb ground movement, vibrations, and thermal expansion. It is specifically designed to bridge the gap between two pipes where a standard push-fit or solvent-weld connection isn’t possible—such as when repairing a cracked section of pipe or joining modern plastic to older clay, cast iron, or concrete systems. Installation is incredibly simple and requires no specialist tools; the coupling is placed over the pipe ends and the professional-grade 304 stainless steel bands are tightened using a standard screwdriver or nut driver. This creates a high-pressure, airtight, and watertight seal that is resistant to root penetration and soil chemicals. Whether you are fixing a broken sewer line or connecting a new extension to an existing drainage network, this flexible coupling provides a reliable, building-regulation-compliant joint that is built to last. Universal Connection: Ideal for joining 110mm (4-inch) pipes made from different materials, including uPVC, Clay, Cast Iron, Ductile Iron, and Concrete. Problem-Solver for Repairs: The easiest way to replace a damaged section of pipe; simply cut out the bad section and “clamp in” a new piece using two flexible couplings. Corrosion Resistant: Features 304-grade stainless steel nut and bolt clamps that won’t rust or degrade when buried in damp or acidic soil. Flexible & Resilient: The EPDM rubber body compensates for minor pipe misalignment and protects the system from damage caused by ground settlement. Airtight & Watertight: Engineered to provide a permanent seal against water leaks and foul odours, even in non-pressurised gravity drainage systems.
