Double-walled drip cap

The double-walled drain plugs from LD Flue's IDRBK series are designed to securely seal the lower end of a double-walled flue system. These drain plugs trap any condensate residue and prevent fluids from leaking outside the system. They are manufactured from high-quality stainless steel with a matt brushed finish and feature a 25 mm or 50 mm thick insulation layer, depending on the diameter. The drain plugs are suitable for use in gas systems, condensing boilers, fuel oil, pellets, wood, and coal. They comply with strict European standards up to and including T600 and are resistant to overpressure up to 5000 Pa and temperatures from 200°C (overpressure) to 600°C (underpressure). Thanks to their modular design, they fit seamlessly into LD Flue's double-walled ID series. Furthermore, these drain plugs can be custom-made by Ventichim and supplied as a ready-to-install product.
