The 160 mm 87.5° equal junction Double or Triple socket is part of our versatile underground drainage range. This junction is formed by one straight pipe with a second pipe set at  87.5° angle. It’s an equal joint so the outlet pipe is the same diameter as the two inlets. Use it to add water from a different source to the first, main flow.
