The supply lines are all PEX crimped, even the fittings so they are not easily replaced like a home supply line.
I have significantly slowed the drip down by rolling up some thread tape lengthwise and shoving it down in the female connector.
I will go find the PEX to pipe thread Shark Bites then use conventional supply lines with shut off valves when time permits.
