Details

The Floplast OS17B connects 21.5mm overflow or condensate piping directly into a larger 32mm (1 1/4″) waste pipe. Specifically, this reducer features a sleek black finish, offering a coordinated alternative to the standard white fittings that typically clutter a drainage run. Floplast uses high-quality uPVC to ensure a robust, airtight seal between mismatched pipe sizes. Consequently, this fitting streamlines your plumbing by allowing condensate lines to discharge into main waste systems efficiently. In short, the OS17B provides a professional, colour-matched solution for complex drainage transitions.

Standard white reducers create a jarring visual break when you try to integrate small condensate lines into larger black waste pipes. This mismatch often makes a professional installation look like a DIY afterthought, especially on prominent exterior walls or under-sink areas. Furthermore, white plastic quickly discolours when exposed to the elements or kitchen grime, leaving your pipework looking aged and neglected. However, the Floplast OS17B Black Reducer solves these aesthetic and practical issues by providing a seamless, low-profile transition. Because the black uPVC matches your existing dark waste systems, the entire assembly fades into the background. Therefore, you can complete your boiler or sink installation with a clean, uniform look that maintains the property’s visual appeal.
