This Ubbink Sekurit PP wall terminal is a concentric flue wall outlet with diameter 60/100. Use it for safe flue gas exhaust and combustion-air supply of a condensing wall boiler through an external wall, in new build and renovation.

The concentric design keeps the boiler efficient and prevents combustion air being drawn from inside the home. The black terminal looks discreet on the façade, while smooth PP resists condensation and moisture. Ideal for DIY installers building an airtight flue system with Sekurit parts.
