Feed-tube assemblies for use with the ALPS Mask emergency system. These high-quality feed tubes are designed so that the ALPS mask can be used as an emergency mask system. All feed tubes incorporate a flow restrictor (.016″) that allows for 3 lpm flow based on the requirement of 1 ltr/10,000 ft. with a toggle-type flow indicator. The feed tubes are available with your choice of connector. Feed tubes are ~4 feet in length. We can make any length upon request.
