Vibrant Performance 3″ 4-Ply Reinforced Silicone Hump Hose Coupler (Blue)

Engineered to absorb vibration, flex, and engine movement in high-performance intake and charge pipe systems, the Vibrant Performance 2734B blue 4-ply aramid-reinforced silicone hump hose coupler provides race-proven reliability for high-boost and extreme-temperature motorsport applications.

Key Features & Performance Benefits

  • ☑ Single-Arch Hump Design: Accommodates motor torque movement, expansion, and minor pipe misalignment without causing stress on hard piping.
  • ☑ 4-Ply Aramid Reinforcement: Hand-wrapped silicone construction prevents ballooning, swelling, and bursting under heavy turbo boost pressures.
  • ☑ Broad Thermal Range: Rated to withstand operating temperatures from -65°F to 350°F (-54°C to 177°C).
  • ☑ SAE J20 Compliance: Meets or exceeds SAE J20 standard specifications for high-performance automotive coolant and charge air service.
  • ☑ UV & Ozone Protection: High-grade silicone resists degradation from sunlight, weather, and under-bonnet environmental exposure.

Frequently Asked Questions

The single-arch hump design allows the coupler to flex and absorb engine vibration, chassis torque, and thermal expansion between rigid hard pipes. This strain relief prevents cracked intercooler end tanks, slipped connections, and distorted aluminum piping under high boost.

No. The Vibrant 2734B hose coupler is designed strictly for intake air, boost charge, water, and engine coolant systems. Silicone degrades when exposed to continuous oil or fuel contact. For fuel or oil service, specialized hose lines such as PTFE-lined stainless steel or oil-resistant fluorosilicone hoses must be used.

Because the hose features a 3.00" (76.2 mm) inside diameter and 4-ply wall thickness, the outer diameter measures approximately 3.35" to 3.40". We recommend using high-quality 3.25" to 3.50" T-bolt clamps or HD stainless steel hose clamps available from JP Racing to secure the connection safely without cutting into the silicone.
