Taukealugs Silicone Straight Coupler 3in ID x 12in Length — 4‑ply 5mm Wall with Stainless T‑Clamps

Taukealugs Straight Silicone Coupler is a heavy-duty 3-inch ID, 12-inch long, 4-ply silicone hose designed for air intake, turbo and intercooler piping with included stainless-steel T-clamps.

This reinforced silicone coupler offers a reliable, universal connection for custom turbocharger, supercharger, compressor and intake systems. Built from a 4-ply silicone construction and a 5 mm wall thickness, the coupler resists UV, ozone and wide temperatures while providing a smooth internal surface to keep airflow steady. Two stainless steel T-clamps are included so you can secure the connection quickly during installation.

How does this coupler withstand under-hood heat and weather?

The Taukealugs coupler is engineered for broad temperature tolerance and environmental resistance. Its silicone compound maintains flexibility and integrity from -140°F to 428°F, while the multi-ply build improves durability against repeated heating cycles and vibration.

• Temperature range: -140°F to 428°F for extreme applications
• UV and ozone resistant to prevent cracking and hardening
• 4-ply, 5 mm thick construction for abrasion and pressure resilience

Will this fit my turbo, intercooler or intake piping setup?

The coupler has a 3-inch (76 mm) inner diameter and a 12-inch (305 mm) overall length, making it suitable for many universal and custom setups. It works well as a straight connector between pipes of matching internal diameter or as part of a charge piping system for turbocharged and supercharged engines.

• ID: 3" (76 mm) to match standard 3" piping
• Length: 12" (305 mm) for flexible placement in charge piping routes
• Universal application across automotive, marine and custom compressor installations

How strong is the coupler under boost and pressure?

The reinforced 4-ply structure and 5 mm wall thickness offer better burst resistance than single-ply hoses. Rated bursting pressure is approximately 2 MPa, and the included stainless steel T-clamps help maintain a secure, leak-resistant seal under typical boost conditions.

• Bursting pressure: 2 MPa for robust performance
• Two stainless steel T-clamps included for reliable fastening
• Smooth inner bore to reduce turbulence and resist blow-off

Are there any installation or safety limits I should know?

The coupler is intended for air handling and charge systems only; it must not be used for fuel or oil transfer. Proper clamp torque and compatible pipe diameters are essential to ensure a leak-free, long-lasting connection. Allow for routing clearance to avoid contact with hot exhaust components or sharp edges.

• Not suitable for fuel or oil transfer — air/charge systems only
• Use correct clamp torque and matching 3" pipe ends for a secure fit
• Keep away from direct exhaust contact and sharp metal edges

Who is this for: Taukealugs’ straight silicone coupler is aimed at DIY enthusiasts, tuners and professional mechanics building or repairing turbocharger, supercharger and intercooler piping systems on cars, trucks, boats and custom compressors. If you need a universal, heat-resistant 3" connector with extra reinforcement and included clamps for immediate installation, this coupler provides a durable, ready-to-fit option. Note: not intended for liquid fuel or oil lines; choose appropriate hoses for those systems.
