Description
The Mishimoto 45-Degree Black Silicone Transition Coupler (MMCP-R45-2025BK) is a four-ply silicone elbow built to reroute coolant lines or air intake system piping through tight, awkward spaces in the engine bay. Constructed from four layers of silicone separated by heat-resistant embedded fibers, this transition elbow carries a maximum temperature rating of 330F, giving it the durability to serve as a dependable link in both coolant circuits and intercooler piping.
Whether you are plumbing a custom air intake system, rerouting coolant lines, or connecting intercooler piping under boost, this 45-degree coupler gives fabricators and DIY installers the flexibility to solve routing problems that straight sections or gentle-bend hoses cannot manage. Its 100-percent silicone construction is designed to resist cracking and hardening, and its high pressure tolerance makes it well suited for use on intercooler pipe connections. Finished in black to complement a variety of engine bays, this coupler is one entry in Mishimoto’s broader lineup of 45-degree transition couplers, which is also offered in blue and red across a range of sizes for both coolant and air passage systems.
Vehicle Applications
This Mishimoto transition coupler is a universal-fit component rather than a vehicle-specific part, making it applicable to custom coolant plumbing, air intake system builds, and intercooler piping projects across a wide range of engine bays. Because it does not ship with hose clamps, installers can select the clamp style that best matches their own coolant or air intake routing setup and pipe diameters.
