Mishimoto Silicone 90 Degree Reducer Coupler 2.5in To 3.25in

Mishimoto Silicone 90 Degree Reducer Coupler 2.5in To 3.25in provides a reliable 90° transition between 2.5" and 3.25" hoses, enabling a consistent seal and controlled routing in coolant and air passage systems.

This coupler is designed to simplify tight routing where a directional change and diameter reduction are required. The silicone construction shown in the product title offers flexible yet stable hose connection for applications that route coolant lines or intake/charge air, allowing clean geometry without kinking or stress at the joint.

Key technical features and why they matter

• 90° geometry — Enables compact directional changes where space is limited; preserves hose alignment and reduces the need for additional fittings.
• Reducer (2.5" to 3.25") — Facilitates transitions between different hose diameters without cutting or custom fabrication, maintaining flow continuity across the joint.
• Silicone construction — Provides elastic sealing and resistance to common coolant and intake system conditions, supporting a consistent, leak-minimizing connection.
• Applicable to coolant and air passage systems — Explicitly suitable for both fluid and charge/intake routing, making it appropriate for OEM repair or performance-related plumbing.

Designed under the Mishimoto name, this coupler integrates into projects requiring reliable hose transitions while preserving routing flexibility. Its form factor reduces installation complexity when adapting hosework for upgrades or repairs.

Use cases

• Directing coolant hoses through tight engine bay spaces where a 90° turn is required.
• Adapting intake or charge-air plumbing where a diameter step is needed without adding rigid fittings.

Technical purchasers and installers will appreciate the straightforward functionality: a silicone 90° reducer that resolves routing and diameter mismatch while supporting dependable sealing in both coolant and air systems.
