Allied - Corrugated Aerosol Tubing is standard blue aerosol tubing that connects to a nebulizer to deliver respiratory medication in the form of a mist. It can be used with a warm or cool aerosol mist and is compatible with a mask or a trach tube. The blue color allows the user to monitor the inside of the tubing and check for build up. It is available in pre-cut 6 inch segements or a roll of 100 feet. The 100 foot length comes in a convenient dispenser box and is segemented every 6 inches, making it easy to cut. The inner diameter is 22 mm. This tubing is latex free.
