Water Leaks

[eric6001]

I have a 2007 16x80 Giles mobile home. I have had issues with leaking at the connections under the sinks in both bathrooms. It is a plastic connection on the end of the water lines that screws onto the threaded part of the faucets, and it seems no matter how tight i get it, it still wants to drip and rund down the lines and keep the inside of my cabinets wet. Any ideas or help greatly appreciated!!

What is the water pressure inside your home? Could you be more specific on what kind of plastic pipe i.e., pvc,pex

I don't have a pressure regulator, so it's just whatever the pressure is coming from the water meter. The hot and cold water supply lines connect to the threaded portion under the faucet with a white plastic screw on fitting. The lines themselves seem to be a hard rubber material, maybe pex, with that screw on nut at the end. This is where they leak.
