What kind of hose for RV pump

[kiknads]

I've got a '16 287bhsw and the rv pump is connected directly to the pex piping. I'm trying to figure out what kind of hose I'll need to connect in the middle to try and reduce the amount of vibration coming through the walls when you use the bathroom sink/toilet. Is there a standard hose I can get somewhere that has the right fittings or is it something I'd have to make

I had a piece of 1/2" RV water hose that I cut enough to make a flexible loop. Its what an RV tech told me they use. Then just pex fittings to connect it.
