About This Product PUNCTURE RESISTANT: Our dryer vent hose is twice as thick as most thin products on the market. Tested for 72 hours and with a load capacity of 16 kg (35 lbs), as shown in the video. Demystify aluminum dryer vent hoses! No more thin, flimsy hoses! Safer: This dryer hose is rated to temperatures up to 107°C (215°F), making it more resistant to heat and aging than PVC pipes, which are prohibited by local building codes and can emit unhealthy plastic odors at high temperatures. Lower Pressure Loss: Our dryer hose is constructed with a tight metal coil and a larger inner diameter aluminum accordion. Exhaust is faster. This design also increases the strength of the hose and reduces vibration and noise. WIDELY USED: The 10cm and 90cm flexible hose can be used in a variety of vents such as clothes dryers, air conditioners, bathroom exhaust fans, and grow tent vents. You will receive a strong and flexible duct that is puncture resistant and requires fewer replacements.
