The BMC silicone reducer 50mm to 70mm (80mm length) is a stepped coupler providing a smooth transition between 50mm and 70mm plumbing over an 80mm span. It serves to adapt mismatched tubing sizes in intake or related systems where a gradual reduction is preferred over an abrupt change. The elongated length helps align components and creates a tidy joint without fabricating custom pieces.
