Vibrant Performance Aramid Reinforced Silicone Reducer Couplers are engineered for high-demand automotive plumbing environments, including forced induction intake tracts and cooling systems. Featuring a multi-layer 4-ply construction, these transition hoses utilize high-temperature resistant aramid reinforcement fabric between each silicone layer to maintain structural integrity under pressure.

This 4.50-inch long coupler allows for a secure, durable transition between 4.00-inch and 3.50-inch OD piping. The aramid reinforcement provides an exceptional operating temperature range, ensuring performance from sub-zero conditions to high-heat engine bay environments. Please note this component is designed for water, coolant, and air service only; it is not compatible with fuel or oil.
