Flex eel polyurethane reinforced hose is an excellent alternative to much bulkier rubber and plastic hoses. Extremely lightweight and tough, it's perfect for either outdoor contractor use or indoor industrial applications. Flex eel retains its flexibility even in cold environments. The integral construction of the hose eliminates the possibility of any separation between the inner tube, braiding and outer cover due to constant expansion and contraction during pulsing operations, such as with nail or staple guns. Assemblies do not include fittings.
