Ailbiuko 4" x 6" Silicone Hump Hose Kit — Blue 4PC, Aramid‑Reinforced with 304 T‑Bolt Clamps

Ailbiuko's 4" x 6" blue silicone hump hoses are reinforced charge-air connectors engineered to replace worn or OEM bumps and deliver reliable, leak-resistant turbo and intercooler joins.

These four 4" inside-diameter, 6" long silicone hump hoses come as a matched set with 304 stainless-steel T-bolt clamps and are built for high-temperature, high-pressure charge-air, intake, and cooling connections. Constructed from 4-ply aramid-reinforced silicone, each hose tolerates extreme thermal cycles and outdoor exposure while maintaining a smooth inner bore to promote airflow. The kit is intended as a direct replacement option for many common aftermarket part numbers and fits a broad range of heavy-duty truck and industrial applications when the dimensions match.

Will these hoses fit my truck or intercooler piping?

Compatibility depends on matching the hose dimensions and application. This kit has a 4.00" (101.6 mm) inside diameter, 4.19" (106.4 mm) outside diameter, and measures 6.00" (152.4 mm) long, with a 0.19" (5 mm) wall and three reinforcement rings.

• Inside diameter: 4.00" (101.6 mm)
• Outside diameter: 4.19" (106.426 mm)
• Length: 6.00" (152.4 mm)
• Wall thickness: 0.19" (5 mm) with 3 reinforcement rings

How does the material and construction improve performance?

The hoses are made from high-temperature, 4-ply aramid-reinforced silicone that resists ozone, UV, and thermal degradation. A smooth inner surface reduces turbulence and pressure drop in the charge-air path, while the reinforcement layers and stainless steel clamps maintain seal integrity under boost and vibration.

• 4-ply aramid reinforcement for strength and pressure tolerance
• Smooth inner bore to minimize airflow resistance
• Temperature range: -40°F to +392°F for wide-operating environments
• 304 stainless T-bolt clamps with self-locking nuts to prevent loosening

Are these hoses safe for different automotive fluids and pressures?

Designed specifically for air and charge-air systems, these silicone hoses are optimized for turbo, intake, and cooling applications but are not compatible with fuel or oil. They are rated for service pressures up to 100 psi, which covers most boosted air systems used in heavy-duty vehicles and industrial equipment.

• Not compatible with fuel or engine oil—air use only
• Maximum working pressure: 100 psi
• Durable across -40°F to +392°F temperature span
• Three reinforcement rings for pressure and shape retention
