I got to looking at my washing machine and thought a couple of elbows might be good to take some strain off the hoses when it's pushed against the wall.

Camco Brass 90 Degrees RV Water Hose Elbow (22505)

Buy any washing machine hoses and use these to turn the corners. Haven't seen hoses with elbows on any shelves but once you have these, you can use any hoses you want to.

Threads are really sharp. One of mine was dinged up which made the thread edges almost dangerous and would give troubles with mating threads. Some dressing with a triangle file smoothed it out fine.
