The Lid - Ø 300 is a versatile and essential component of the SWPro modular single wall flue system. Made from high-grade 316L stainless steel, this cap end is designed to close off the branch or base of a tee or the end of a header securely. The system is constructed with high-pressure sealing gaskets (P1/H1), making it suitable for both high and low-temperature applications, including non-condensing and condensing environments.
This makes it ideal for boilers, ovens, ventilation systems, and chimney shaft liners. Certified with CE marking and complying with EN 1856-1 standards, the SWPro system ensures safety and reliability. Installation is straightforward with a push-fit jointing system secured by a locking band, and jointing gaskets are required for P1 and H1 installations.
Maintain a safe distance of 50mm from any combustible materials during installation for optimal performance and safety.
