The Ticon 4-ply black 3.5in to 4.0in silicone reducer provides a reinforced silicone transition between 3.5" and 4.0" piping. Four-ply construction adds strength and stability while preserving a smooth interior passage through the diameter change. It’s suitable for adapting aftermarket intake or charge plumbing where a reliable, flexible reducer is required to join mismatched pipe sizes.
