Taigoehua 3" (76mm) Straight Silicone Hose Coupler 12" Long — 4-Ply Reinforced, 5mm Wall with 2 Stainless T-Bolt Clamps

Taigoehua's 3" (76mm) straight silicone hose coupler is a 12" long, 4-ply reinforced, 5mm-thick intake/charge pipe sleeve supplied with two stainless T-bolt clamps for reliable turbo and intercooler connections.

This heavy-duty silicone coupler is built for forced-induction and custom intake systems where flexibility, heat resistance, and pressure durability matter. Constructed from multi-layer reinforced silicone, it tolerates extreme temperatures and repeated clamp cycles while providing a smooth, low-restriction transition between turbocharger, intercooler, charge pipe, or air intake components. It ships with two stainless steel T-bolt clamps sized to secure a leak-resistant seal on 76mm fittings.

What are the core specifications and materials?

The Taigoehua coupler is a 3" (76mm) inner diameter, 12" (305mm) long silicone sleeve with 5mm wall thickness and four reinforcement plies. Temperature range and pressure ratings are engineered for demanding under-hood conditions.

• ID: 3 in / 76 mm
• Length: 12 in / 305 mm
• Wall thickness: 5 mm, 4-ply reinforcement
• Temperature range: -140°F to 428°F (-95°C to 220°C)
• Bursting pressure: 2 MPa (approx. 290 psi)

How does it perform under boost and heat?

Designed for turbo and supercharger plumbing, the reinforced silicone construction resists deformation under boost and remains flexible in cold starts. The rated bursting pressure and wide temperature tolerance minimize the chance of blowoffs or premature hardening compared with single-layer hoses.

• 4-ply reinforcement improves creep and burst resistance
• High-temperature silicone resists softening at elevated intake temperatures
• Cold tolerance prevents cracking in freezing environments

What comes in the package and how does installation look?

Each package includes one straight silicone coupler and two stainless steel T-bolt clamps sized for a secure fit on 76mm connections. The clamps provide even radial pressure to reduce pinch points and ensure a consistent seal when tightened to recommended torque.

• 1× 3" ID x 12" length silicone coupler (5mm wall)
• 2× stainless steel T-bolt clamps for strong, uniform clamping
• Simple fit-over installation on intercooler, charge pipe, or intake tube ends

Where should this not be used and compatibility notes?

This silicone coupler is intended for air, charge, and coolant-adjacent plumbing in forced-induction and intake systems, but it is not suitable for transferring fuel or engine oil. Always verify physical clearances and clamp torque requirements on your specific vehicle or application before final assembly.

• Not rated for fuel or oil transfer—use only for air/charge plumbing
• Best for custom turbo, supercharger, intercooler, and intake connections
• Check hose length and bend requirements for tight engine bay routing

Who is this for: Automotive enthusiasts, tuners, and fabricators building or repairing turbocharged and supercharged intake systems who need a durable, heat-resistant, and flexible 3" coupler for custom charge piping, intercooler connections, or replacement intake segments. It suits DIY installations, garage shops, and marine or off-road projects where a reliable silicone transition and stainless clamps are required.
