Key Features and Benefits
Robust Construction: The pipe features a dual-layer construction with a 316L stainless steel inner layer and a 304 stainless steel outer layer. This combination provides superior resistance to high temperatures and corrosive substances, ensuring that your system remains durable over time.

Secure Installation Mechanism: With its innovative 8-barbed twist lock mechanism, the Sflue pipe ensures that connections between sections are both secure and simple to assemble. The inclusion of a locking band further guarantees that the pipe remains firmly in place, reducing the risk of leaks or accidental disconnections.
Safety and Compliance: Safety is paramount, and the Sflue pipe is HETAS approved and CE marked, conforming to rigorous industry standards. A key safety feature is the mandated 50mm distance to combustibles, which helps to prevent overheating and fire hazards.
