Construction & Design

The Turbosmart Silicone Straight Coupler is constructed from multiple layers of high-quality silicone, reinforced with a polyester fabric braid that provides exceptional strength and pressure resistance. Its one-piece design eliminates weak points and ensures a uniform, seamless appearance. The coupler's smooth interior surface minimizes airflow turbulence, promoting efficient airflow and reducing pressure drops within your system.

The black silicone material is formulated to withstand extreme temperatures and environmental conditions, including exposure to oil, coolant, and other automotive fluids. Its flexible nature allows for easy installation and routing, even in tight spaces, while maintaining a secure, leak-free connection. The coupler's durable construction ensures it will perform reliably over many miles and years of use.

Performance & Sound

While this silicone coupler is primarily designed for durability and reliability, it also contributes to improved system performance by maintaining consistent airflow and preventing leaks. Its high-quality construction helps support optimal boost levels and reduces the risk of hose failure under high-pressure conditions. Although it does not significantly alter engine sound, its robust design ensures quiet, secure operation in your charged-air system.
