Sleeve 3.75in Diameter x 2.00in Length

The Vortech Silicone Coupling (PN 7S375-200) is a precision-molded straight silicone reducing sleeve designed to connect mismatched tubing diameters in supercharged and turbocharged intake or charge piping systems. This coupler transitions from a 3.75-inch inside diameter to a 2.00-inch inside diameter, making it ideal for custom fabrication, intercooler plumbing, and supercharger inlet or discharge routing.

Constructed from reinforced, high-temperature silicone, this coupling is built to withstand the elevated heat and pressure associated with forced-induction applications. Its reinforced construction resists expansion under pressure, maintaining consistent airflow and reducing the risk of leaks. The blue finish provides easy visual identification.
