Product review (5 stars): Good Quality
This is a good quality flexible braided stainless line. The connectors are easy to use and watertight. As indicated on the product label, hand tighten the line and then apply 1/2 additional turn with a wrench, don't overtighten.
Also, don't use any pipe dope or teflon tape, as they're not needed and using either may interfere with making a good compression seal.
