The BMC silicone reducer 70mm to 85mm (80mm length) is a molded stepped coupler designed to expand a 70mm inlet to an 85mm outlet across an 80mm section. It simplifies diameter changes in intake or related plumbing by providing a single, purpose-built piece that aligns components and minimizes connections. The fixed length assists in maintaining a consistent run when adapting differing tubing sizes.
