125mm (5 inch) Black

All black of Convesa KC components found in the range below has been manufactured with an internal diameter of 125mm (5 inches), a 30mm layer of compressed Rockwool insulation and an outer diameter of 175mm (7 inches). Therefore, brackets, supports, and collars are designed to secure around the greater external diameter. Any item that requires a locking band to create a connection comes with one included.

These 125mm twin wall flue pipes are manufactured from high-quality stainless steel which is then powder coated to a matte black finish to suit our black finish range. Our black 125mm twinwall pipe boasts excellent insulating properties, secure locking bands already attached, fully welded twin walls and an impressive twelve-year warranty for long-term peace of mind. By simply selecting the appropriate adaptor, you can easily and safely connect the Convesa KC twinwall pipes to the Vitreous enamelled pipes and flexible flue liners.
