Repair a leaky RO system
RO system had started a leak and this was the part that leaked. Very easy to replace. Turn off system. Remove the old part, cut off a small piece of each hose end to make sure that an unmarred part of the hose goes inside the new fitting for a watertight fit. Push/twist on the new part.
