The Triplelock Flue Bug Ø 125 is an essential gas terminal cowl designed to terminate a liner in gas-fired appliances while maintaining your existing chimney pot. Perfect for installations where removing the chimney pot is not desirable, this cowl securely attaches the flue liner to the inner tube and the chimney pot. It is vital to note that a Jubilee Strap, required for securing the flue liner, is sold separately.

Regular maintenance is critical for this product; we recommend that chimneys dedicated to gas and oil appliances be swept and inspected at least once a year to ensure optimal performance. Designed to high standards, the Triplelock Flue Bug is a reliable solution for efficient and safe flue system operation.
