Mishimoto Silicone Reducer Coupler 45 Degree 3in-3.25in Red

Mishimoto Silicone Reducer Coupler 45 Degree 3in-3.25in Red is a 45-degree silicone reducer coupler designed to join 3.00" and 3.25" diameter hoses while providing reliable thermal and pressure compatibility for both coolant and air passage systems.

This coupler is offered by Mishimoto, a brand known for engineered silicone solutions for automotive fluid and air routing. The 45-degree transition shape simplifies routing in tight engine bays and helps maintain a consistent internal flow path when changing hose diameter.

Key technical features and why they matter

• 45-degree transition geometry — Enables smooth directional change and compact routing while maintaining consistent hose alignment.
• 3.00" to 3.25" reducer sizing — Provides a precise diameter transition for connecting hoses with those nominal internal dimensions without adapter stacks.
• Silicone construction — Compatible for use in coolant and air passage systems, offering material resilience to common automotive temperature cycles and exposure found in those systems.
• High-visibility red finish — Facilitates visual inspection and integrates with red-themed engine bay components where aesthetic coordination is desired.

Use this reducer coupler where a compact 45-degree diameter change is required between 3.00" and 3.25" hoses in coolant or air routing applications. The part simplifies installations that need a single-piece, angled transition and supports straightforward clamping at each end.
