I have a kitchen sink faucet where the metal sheath on the pullout spray
head tubing has come loose at the spray head end. It's a Kohler single
lever faucet, white plastic, model number unknown; the spray head itself
appears to be part number 75167.
There seems to be a ferrule of some sort inside the screw-on fitting at the
end of the tube, but I can't tell if it was crimped onto the sheath, or
perhaps welded. Anyway, before I operate, would anyone know if these things
are DIY repairable, or do I have to find a whole new tubing assembly?
