The BMC silicone reducer 65mm to 70mm (80mm length) is a short stepped coupler engineered to adapt 65mm to 70mm plumbing over an 80mm run. It provides a concise transition useful in custom intake work or when replacing sections of piping with slightly different diameters. Using a single molded reducer simplifies installation and reduces the number of joints in a routed air path.
