VIVOSUN 2-Pack 4-Inch Aluminum Ducting | 25 ft Flexible Dryer Vent Hose with Stainless Steel Clamps

Improve airflow in homes, studios, and small workplaces with the VIVOSUN 2-Pack 4-Inch Aluminum Ducting. Each 25-foot run is built from heat-resistant aluminum and designed to stay flexible, helping you route air around obstacles without kinking or collapsing.

With two ducts and four stainless steel clamps, this set delivers a straightforward, dependable setup for dryer exhaust, bathroom vents, kitchen hoods, or general ventilation. The multi-layer construction combines an inner and outer aluminum foil layer with a PET thermoplastic middle, delivering durability and a leak-minimizing profile while maintaining a light footprint for easy handling.

Durable, versatile, and easy to install

• Premium material: aluminum resists high temperatures and corrosion for long-term use.
• Multi-layer protection: inner/outer foil plus PET layer guard against tears and leaks; flame-retardant features add peace of mind.
• Flexible design: built-in steel wire enables easy shaping to fit around corners and through tight spaces.
• Secure connections: rustproof stainless steel clamps ensure tight, dependable joints.
• Broad applications: ideal for HVAC ventilation, dryer venting, bathroom exhaust, kitchen vents, plant rooms, or warmhouse air circulation.

Installation tips and practical use cases

• Match duct size to fan diameter for a tight, leak-proof fit (e.g., pair a 4" fan with 4" ducting).
• Portable and lightweight design supports quick deployment in closets, equipment rooms, or temporary setups.
