Mishimoto Silicone Transition Coupler

The Mishimoto Silicone Transition Coupler is a silicone hose coupler, also called a reducer coupler or hose adapter. It joins two hoses or pipes of different diameters in coolant, intake, intercooler, and other forced-induction plumbing. It works well for custom piping, performance upgrades, and replacing worn rubber connectors.

Key Features:

• Silicone construction resists heat, oil, and the wear of everyday use
• Reinforced, multi-ply build is designed to handle boost pressure and engine vibration
• Flexible design absorbs movement and misalignment between connected components
• Smooth transition between diameters helps keep flow consistent
• Lasts longer than standard rubber couplers in demanding conditions

Mishimoto is known for engineering cooling and performance parts for enthusiasts. This coupler line gives you a dependable, flexible connection for street, track, and custom builds. Hose clamps are used to secure the coupler and are typically purchased separately unless the listing says otherwise.
