Mishimoto MMCP-R90-2025BK Silicone Transition Coupler - 90-Degree 2.00-In to 2.50-In Black

The Mishimoto MMCP-R90-2025BK is a 90-degree silicone transition coupler designed to simplify the routing of complex coolant or intercooler piping. Transitioning from a 2.00-inch to a 2.50-inch inner diameter, this reducer coupler makes it easy to connect pipes of different sizes at a right angle — a common challenge in custom and performance engine builds.

Constructed from 100% silicone with four reinforcing layers divided by embedded heat-resistant fibers, this coupler delivers exceptional durability and pressure resistance in demanding underhood environments. It is rated for continuous use at temperatures up to 330°F and is built to handle the high boost pressures found in turbocharged and supercharged intercooler pipe systems.

Key Features:

• 90-degree bend with transition from 2.00-in to 2.50-in inner diameter
• 100% silicone construction for superior flexibility and longevity
• Four-layer silicone wall reinforced with embedded heat-resistant fibers
• Temperature rated up to 330°F for high-heat applications
• High-pressure tolerance — ideal for intercooler pipe connections
• Suitable for both coolant and air/boost systems
• Available in black, blue, and red to complement any engine bay
• Backed by the Mishimoto Lifetime Warranty

The MMCP-R90-2025BK is finished in gloss black and integrates cleanly into performance builds where a reliable, heat-resistant silicone coupler is needed to navigate tight or complex pipe runs.
