The Boiler adaptor - Ø 400 is an essential part of the SWPro modular single wall flue system. Made from superior 316L grade stainless steel, this adaptor is designed to connect the flue system securely to the appliance. Featuring a high-pressure sealing gasket (P1/H1), the SWPro system is versatile enough to handle both high and low temperatures, accommodating both non-condensing and condensing applications with flue gases in positive and negative pressure.

The construction uses high-grade 316L stainless steel, varying in thickness based on the flue diameter to ensure optimum durability and performance.

For accurate and safe installation, jointing gaskets are necessary for every joint in P1 and H1 installations.
