I assume that everyone is using brass compression fittings with thimble and 1/2″ pipe nipple to replace the plastic hose fittings Pearson used. If you haven’t replaced all these already, I suggest that you do so before they fail.
You can buy short flexible hoses with female pipe fittings that are sold to connect to faucets to make installation easier. If the plastic hoses are too short, you can attach these directly to the pipe nipples. If you buy and replacement tubing, make sure it is rated for hot water. The water in our water heaters can get pretty hot. Hot enough to cause inexpensive tubing to soften and pull out of the compression fitting no matter how tight you make them.
At one time, Home Depot sold compression fittings with female pipe adapters that would screw directly onto the faucet bottoms. I can’t find them anymore. They also sold nylon compression rings. The brass rings work, but you have to torque the fitting down pretty hard to compress them.

Hi Rich,
I use the squeeze together fittings – you just take the 3/8″ plastic tube and stick it about 3/4″ into the fitting and it's done. It's rated for over 100 psi, like 160 deg F, and is used in new housing for domestic water and radiant heating. They have the appropriate fittings for pipe to tubing and the really nice thing is that you can pull the tabby thingy out and disconnect the tubing without destroying the end.
They run between 1.50 to 7.00 each (valves are expensive) and they come in 3/8″ and 1/2″ sizes (our boats are 3/8″ id, 1/2″ od).
