Mishimoto Silicone 90 Degree Reducer Coupler 3in-3.75in

Mishimoto Silicone 90 Degree Reducer Coupler 3in-3.75in provides a reliable 90-degree transition between 3.00" and 3.75" plumbing while improving joint durability in coolant and air passage systems.

This coupler is part of the Mishimoto line of silicone couplers designed for repeatable, long-term service across a wide range of piping applications. The product is intended for projects requiring a right-angle reducer where silicone construction and precise fit are preferred for system longevity and ease of installation.

• 90-degree transition design — Allows direction change without cutting or bending tubing, preserving flow paths and simplifying routing.
• Reducer sizing: 3.00" to 3.75" — Provides a step-down connection between different diameter pipes, enabling integration between mismatched components without adapters.
• Silicone construction — Engineered for resistance to temperature cycling and common fluids in coolant and air passage systems, which helps maintain a consistent seal over time.
• Applicability to coolant and air systems — Suitable for both liquid and charge-air routing where silicone material properties and a molded 90-degree profile are required.
• Mishimoto brand — Part of an expansive line from Mishimoto, offering compatibility with a broad range of sizes and reducing the time required to source the correct coupler for a project.

Why these features matter: the molded 90-degree shape avoids sharp kinks and stress points that can occur when bending rigid piping or using multiple straight couplers. The reducer geometry eliminates the need for complex transitions, and silicone material contributes to vibration damping and resistance to degradation from thermal cycling.

Installation notes: select appropriate clamps and torque to manufacturer recommendations for the mating components. Confirm the inner diameters of mating pipes match nominal sizing to ensure a secure, leak-free fit.
