Vortech Silicone Coupling 4.50" x 2.50" Straight Sleeve - Blue 7S450-250
Blue Straight Reducing Silicone Coupler for Large-Diameter Boosted Plumbing
The :contentReference[oaicite:0]{index=0} Silicone Coupling (PN 7S450-250) is a precision-molded straight silicone reducing sleeve designed to connect large-diameter intake or charge piping to smaller tubing in supercharged and turbocharged systems. This coupler transitions from a 4.50-inch inside diameter to a 2.50-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 engineered to withstand the elevated heat and pressure associated with forced-induction applications while maintaining the flexibility needed to absorb engine movement and vibration.
Boost-Ready Silicone Construction
Unlike standard rubber connectors, Vortech silicone couplers are purpose-built for boosted environments. The reinforced silicone construction resists expansion under pressure, helping maintain consistent airflow and reducing the risk of leaks or coupler failure under load.
The straight reducing design provides a smooth, controlled airflow transition between pipe sizes without abrupt changes, supporting efficient airflow and long-term reliability for both street-driven and race-focused builds.
