Vortech Silicone Coupling 3.25" Diameter x 1.00" Straight Sleeve - Blue 7S325-100
Blue Straight Reducing Silicone Coupler for Specialized Boosted Plumbing
The :contentReference[oaicite:0]{index=0} Silicone Coupling (PN 7S325-100) is a precision-molded straight silicone reducing sleeve designed to connect large-diameter tubing to small auxiliary connections in supercharged and turbocharged intake or charge piping systems. This coupler transitions from a 3.25-inch inside diameter to a 1.00-inch inside diameter, making it ideal for custom fabrication, vacuum reference routing, or specialized airflow plumbing in forced-induction builds.
Constructed from reinforced, high-temperature silicone, this sleeve is engineered to handle the heat and pressure demands of boosted applications while remaining flexible enough to absorb engine movement and vibration.
Boost-Ready Silicone Construction
Unlike standard rubber connectors, Vortech silicone couplers are purpose-built for forced-induction 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 clean, controlled airflow transition between pipe sizes, supporting system integrity and long-term reliability in both street and race applications.
