Green Quick Sink tubing is our easiest option to install, featuring a thinner, more flexible wall that makes it lighter and easier to handle while also allowing it to withstand higher operating pressures.

Always install a heat-resistant tubing whip between the compressor and Quick Sink tubing. Connect the whip to the compressor first, then connect the Quick Sink tubing to the whip.
