Mishimoto Silicone Reducer Coupler 90 Deg 2.25in 2.5in Red

Silicone reducer coupler — the Mishimoto Silicone Reducer Coupler 90 Deg 2.25in 2.5in Red provides a compact 90-degree transition with reliable diameter reduction for coolant and air passage systems.

This coupler is part of Mishimoto’s expanding line of silicone couplers, engineered to offer a broad selection of 90-degree transition options for use where routing and diameter change are required. Its 2.25in to 2.5in reduction and dedicated 90-degree geometry address spatial constraints while preserving flow continuity.

Key features and why they matter

• 90-degree transition — enables tight routing in confined engine bays and system layouts where a right-angle change is required, reducing the need for additional fittings or bends.
• 2.25in to 2.5in reducer — matches mismatched service lines or components with a small step in diameter, simplifying integration between different hose sizes.
• Silicone construction — designed for use in both coolant and air passage systems, providing material compatibility for common engine bay fluids and intake applications.
• Red finish — provides a visual indicator of the transition and aligns with aftermarket engine-bay styling without affecting function.
• Mishimoto brand — part of Mishimoto’s broad range of silicone couplers, offering consistency with the company’s established product family and application breadth.

Performance and application notes

Use this 90-degree silicone reducer coupler where a compact, angled transition between 2.25in and 2.5in lines is required. Its intended applications include coolant routing and air passage systems, making it suitable for projects that need a durable, flexible coupling solution while minimizing additional plumbing complexity.

This product expands options for builders and technicians seeking a dedicated reducer with a 90-degree profile from Mishimoto’s silicone coupler lineup.
