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 rated at 16 kg (35 lbs) load capacity, as shown in the video. Demystify aluminum vent hoses! No more thin, flimsy hoses! Strong and Durable! 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 noxious plastic odors at high temperatures. LOWER PRESSURE LOSS: Our dryer hose is constructed with a tight metal spiral 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 1.8m 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, flexible duct that is puncture-resistant and requires fewer replacements.
