Introducing the Boiler adaptor - Ø 450, a key component of the SWPro modular single wall flue system. Constructed from high-grade 316L stainless steel, this adaptor ensures optimal performance and longevity. Whether it's for high or low temperature, non-condensing, or condensing applications, our flue adaptor is versatile enough to handle it all.

CE marked and conforming to EN 1856-1 standards, the Boiler Adaptor is equipped with a high-pressure P1/H1 sealing gasket, making it suitable for positive and negative pressure environments. Ideal for connecting boilers, ovens, ventilation systems, and as a chimney shaft liner, this adaptor ensures safe and efficient operation. Installing the SWPro is a breeze with its modular push-fit jointing system, secured by a locking band.

For P1 and H1 setups, joint gaskets are essential at every connection, and maintaining a 50mm distance from combustible materials is crucial. When used on condensing appliances, ensure a silicone sealant or an appliance-incorporated seal at the outlet for added security.
