Fernco (previously known as Flexseal) manufactures an internal coupling specifically designed to create a strong permanent connection whilst having minimal impact to natural flow. The tapered edges aid flow and a thin coupling wall keeps bore reduction to a minimum.

The connection process couldn’t be easier. Simply clean the internal surface of the pipes to be connected, push the coupling into the problem pipe and push the connecting pipe over the opposite end of the coupling. Designed to provide a reliable friction fit, these couplings are strong and long-lasting.

• Quick and easy to install
• Superior joint stability compared to external couplings
• Pushfit connection – no tools required
• Watertight connection on any pipe material
• No need to expose external surface of pipe
• Pipe stop indicates that the product is properly installed, when it is flush to the pipe end
• Withstands internal pressure of up to 2.5 bar
• Conforms to the requirements of BS EN 295-4:2013
