Taukealugs 4in 90° Silicone Elbow Coupler 4.0in ID — 120mm Length, 4‑Ply with 2 T‑Bolt Clamps

Taukealugs 90° 4-ply silicone elbow coupler is a 4.0" (102mm) inner-diameter, 120mm-length turbo/intercooler connector built to handle high temperatures and boost pressures while including two T-bolt clamps for secure installation.

This reinforced silicone elbow is designed for connecting turbo, intercooler, or intake piping where a compact 90-degree bend is needed. Constructed from four-layer silicone with a 5mm wall, it resists heat, oil, and pressure swings commonly found in forced-induction and performance intake systems. The package includes two heavy-duty T-bolt clamps sized to fit the coupler so you can install it right away without searching for extra hardware.

How does this elbow hold up to heat and pressure?

The 4-ply construction and specified operating range make this elbow suitable for elevated under-hood temps and pressurized boost lines. It tolerates low temperatures down to -60°C (-76°F) and high temperatures up to 230°C (446°F), and its burst rating is 2 MPa for reliable performance under boost.

• 4-ply reinforced silicone resists deformation under pressure.
• Rated max temperature 230°C and min -60°C for wide climate use.
• Bursting pressure approximately 2 MPa for boosted systems.
• 5 mm wall thickness for durability and kink resistance.

Will it fit my 4" turbo or intercooler piping?

The internal diameter measures 4.0" (102 mm), matching standard 4-inch plumbing commonly used on turbochargers and intercoolers. The 120 mm length (one leg) and 90° angle are suited for tight-routing scenarios where a short, robust elbow is required.

• Inner diameter: 4.0" (102 mm) for standard 4-inch systems.
• Length: 120 mm on one leg for compact installations.
• 90° bend ideal for routing between turbo and intercooler or intake sections.
• Comes with two T-bolt clamps for secure, leak-resistant connections.

How easy is installation and maintenance?

Installation is straightforward: slide the elbow over the piping and tighten the included T-bolt clamps to the recommended torque. Silicone’s smooth interior also helps prevent residue buildup, and occasional inspection of clamps and hose condition is all that’s typically required.

• Includes two heavy-duty T-bolt clamps—no separate clamp purchase needed.
• Silicone interior reduces debris adhesion and eases cleaning.
• Simple clamp-tighten installation—compatible with standard workshop tools.
• Periodic visual check recommended for clamp tension and hose integrity.

Who is this for: This 90° 4-ply silicone elbow is made for DIY tuners, performance shops, and vehicle owners upgrading or repairing turbo, intercooler, or intake piping that requires a durable, heat-resistant 4-inch elbow. It suits applications needing a short-radius 90° turn with secure clamping and long-term resilience against heat, oil, and pressure variations.
