This stainless steel Soil Pipe Adaptor is suitable for 1/4" and 3/8" hose.
This product gives you a quick, simple and secure way of draining waste from a 1/4" or 3/8" hose into a soil pipe.
Simply drill a suitably sized hole in the soil-pipe, insert this adapter and tighten the bolt on the outside to expand the rubber seal. (Note: you do not need access to the inside of the soil pipe to fit this product).
