The S9 Series SlimLine Tubing Wrap helps to insulate the hose from the cooler, ambient room air. As a result, the Tubing Wrap helps to stop rainout and reduce tubing drag.,This tube wrapping may be used with both SlimLine and ClimateLine tubing. Do note that while the tube wrapping fits the SlimLine from end to end, due to its larger diameter, the ClimateLine will not fit fully (about 7 inches exposed).
