I would just go brass for durability and safer in the first place.....
the plastic ones are good for outside garden hoses, but what really concerns me is the HOT side, they weren't designed to handle that high of a temp....
mine also have seperate valves for each side.....I think they ran 6.00 each at Lowes...
I also know it seems redundant to re-spin in the FLer, but this allows you to play with the SQ, and yet still be efficient for the dryer, without buying a seperate spinner, you already have one!.....I like re-spinning in the twintub, for only 5 minutes, just to see how much more water I can get out before the dryer...for towels, usually about 6 cups, thats a lot for the dryer to remove if you think about it.....if you can, take a load from the SQ and spin it in the FLer, and put your drain hose in a bucket, just out of curiosity to see how much more water you get out of it!.....
