Mishimoto Silicone Reducer Coupler 90 Deg 3.5in To 4in Red

The Mishimoto Silicone Reducer Coupler 90 Deg 3.5in To 4in Red provides a 90-degree silicone transition from 3.5" to 4" piping, enabling a reliable connection for coolant and air passage systems.

Designed by Mishimoto, this reducer coupler is part of an expanding lineup of 90-degree transition couplers intended for use where compact routing and consistent sealing are required in both coolant and intake plumbing.

• Material: Silicone — compatible with coolant and air passage applications, allowing flexible routing where rigid piping is impractical.
• Angle: 90-degree transition — simplifies tight installations by changing flow direction without additional fittings.
• Size: 3.5in to 4in reducer — provides a precise step between mismatched tubing diameters, maintaining continuity of flow between different components.
• Color: Red — visually identifiable routing and brand-consistent styling for organized engine bays.
• Brand: Mishimoto — from a specialist supplier known for focused cooling and intake solutions, ensuring product selection across a wide range of applications.

Application notes: This 90-degree reducer is intended for use in both coolant and air passage systems. Its reducer geometry is targeted at projects requiring a transitional coupling between 3.5" and 4" lines while changing direction by ninety degrees.

Installation considerations: Use appropriate clamps sized for 3.5" and 4" connections and ensure hose seats fully on each end of the coupler to maintain consistent sealing in both coolant and intake circuits.
