4 Ply Reducer Coupling 2 .75in x 3.25in x 3in lon

The 4 Ply Reducer Coupling 2.75in x 3.25in x 3in Long from Vibrant Performance is an essential component for custom automotive builds, turbo installations, and performance engine modifications. This reducer coupling is designed to bridge diameter transitions in forced-induction systems and intercooler piping, making it ideal for applications where a reduction from larger to smaller tubing is necessary.

Constructed with 4-ply reinforced silicone, this coupling features an inlet diameter of 3.25 inches and an outlet diameter of 2.75 inches, with a length of 3 inches. This design ensures optimal wall thickness and durability under boost and high-temperature cycling, resisting collapse under vacuum and maintaining structural integrity during thermal expansion. The internal taper promotes smooth airflow transition, reducing pressure drop and turbulence.

This reducer coupling is particularly beneficial for builders working on turbo manifold transitions and post-intercooler applications, where maintaining airflow efficiency is critical. Its lightweight design at just 0.23 lbs minimizes added mass in engine bays, making it suitable for both street and mild competition use.
