I have a Lite In the Box kitchen faucet that provides two flexible supply tubes for attaching to water supply. These supply tubes have two o-rings on the faucet end and are attached last in the installation process since the mounting adapter is too small in diameter to allow the tubes to pass through. The pictures from the company web site show the tubes being installed last into the mounted faucet that must have been hand tightened.
Given this problem and no experience with supply tubes like these I want to be sure I understand the installation and that these sorts of tubes will not leak using the installation method. There is a requirement for an adapter to attach these tubes to the existing plumbing which is separate.
