Mishimoto Silicone 90 Degree Reducer Coupler 2in To 3in Red

Mishimoto Silicone 90 Degree Reducer Coupler 2in To 3in Red provides a reinforced 90-degree transition coupler designed to deliver a reliable routing solution for coolant and air passage systems, simplifying plumbing runs while maintaining consistent connections for performance and durability.

This Mishimoto coupler is intended for applications where a compact 90-degree bend and a size reduction from 3" to 2" are required, making it suitable for tight engine bays, intercooler plumbing, and coolant line reroutes on both street and track vehicles.

• 90-degree transition: Allows tight routing in confined spaces while avoiding sharp kinks; useful where a smooth change in direction improves packaging and reduces stress on adjacent hoses.
• 2in to 3in reducer: Provides a secure diameter transition between mismatched lines, enabling integration of different hose or pipe sizes without adapters that add length or potential leak points.
• Silicone construction: Flexible and resistant to typical automotive fluids and temperature variation, offering consistent sealing performance in both coolant and air systems.
• Red finish: Visually identifiable in engine bays for maintenance and routing checks; matches red-themed OEM or aftermarket plumbing for a coordinated appearance.
• Mishimoto engineering: Designed and specified by Mishimoto to fit within a broad selection of coolant and air passage applications, leveraging the brand’s reputation for quality thermal and plumbing components.

Why it matters: Using a purpose-built silicone 90-degree reducer minimizes custom fabrication, reduces the number of clamps and joints required, and helps maintain airflow or coolant routing integrity. The unit supports applications ranging from intercooler plumbing in a turbo upgrade to coolant reroutes where space and reliability are priorities.
