Description
The Mishimoto MMCP-1375SBK is a 1.375-inch straight silicone coupler built for custom air intake and coolant piping projects. Molded from 100-percent silicone with embedded heat-resistant fibers, this black coupler is engineered to handle high heat and pressure while joining sections of tubing on your air intake system or cooling circuit.
Whether you’re piecing together a custom cold air intake, tying in intercooler piping, or routing coolant lines, a quality silicone coupler is the connection point that keeps everything sealed and secure. This Mishimoto coupler is rated to withstand up to 330°F and is coolant compatible, making it a versatile choice for enthusiasts building or upgrading an air intake filter setup, a cool air intake routing, or a coolant hose run that needs a dependable, leak-resistant joint. Its straight shape and 1.375in inside diameter make it easy to splice into existing intake or cooling tubing without altering hose angles.
Vehicle Applications
This is a universal-fit silicone coupler, not tied to a specific make, model, or engine code, which means it can be used across a wide range of custom intake, turbo, or coolant plumbing builds where a 1.375-inch straight connection is needed. Because it isn’t application-specific, it’s a practical component for fabricators and DIYers assembling their own cold air intake systems or coolant lines rather than a direct-fit replacement part for a single vehicle.
