TuoLauthon 90 Degree Silicone Reducer Coupler Hose – 1.5–1.75 in, 4-Ply Reinforced, 4 in Legs, Clamps Included

Overview

The TuoLauthon 90 Degree Silicone Reducer Coupler Hose is purpose-built for Turbo, Intercooler, and Intake piping upgrades. An elbow-style connector with a 1.5–1.75 inch internal diameter, it helps you achieve clean transitions in tight engine bays. Each hose leg measures about 102 mm (4 inches), offering a balanced profile for a variety of configurations without adding excess length.

Crafted from high-quality silicone with four-ply reinforcement, this reducer hose combines rigidity with flexible handling. The thick 5 mm wall enhances durability where hoses meet bends and heat, while maintaining a smooth interior for steady airflow and reduced turbulence.

Key Features

• Durable construction: 4-ply reinforced silicone with approximately 5 mm wall thickness for long-lasting performance.
• Elbow design: 90-degree angle to ease routing in compact engine bays and tight piping paths.
• Wide heat tolerance: designed to perform in high-temperature environments typical of turbo and intercooler routing.
• UV, water, and ozone resistance: stability in varied conditions helps preserve flexibility and appearance.
• Temperature and pressure range: robust enough to handle high heat and operating pressures commonly seen in performance setups.
• Not for oil or fuel transfer: suitable for air and intake-related piping within universal compatibility.

Fitment & Usage

Designed as a universal elbow connector, this hose adapts standard turbo, intercooler, and intake piping to a 90-degree transition. It is ideal for enthusiasts looking to upgrade piping routing, reduce bottlenecks, or tailor a system to a specific engine bay layout. Visioned for performance-minded builds, it offers a reliable option where a rigid 90-degree bend is desirable while resisting common engine bay challenges such as heat and exposure to the elements.

Care & Installation Considerations

Professional installation is recommended to ensure a precise fit. Inspect clamps and hose ends for a secure seal after installation. Routine checks during service intervals help maintain consistent performance, especially in high-heat environments. Note that oil and fuel transfer should use components designed specifically for those fluids.

Notes

Size tolerance is approximately +/- 0.5 mm. This product is not designed for oil or fuel transfer systems. The included clamps enable fast, secure mounting during installation.
