Product review (5 stars): This hose did the job
Needed to install washer further away from slop sink and input water.  Purchased 10 feet hoses at same time and you can look up my review if you have same need.

This drain hose was a bit odd in appearance as I expected something that would install on washer.  Instead, this slips over the existing drain hose.  I bought two stainless steel hose clamps (the type with screw to tighten clamp-I don't think I would trust the other kind that uses just spring tension)as I was bit concerned about leaking.  It does not feel like a really tight fit when slipping the drain hose over the existing washer hose.  But, two clamps seem to hold things.

Another solution to problem found picking through Amazon's offerings.
