BTW, when he looked at the original gray hose that Thor used he felt that the male mating surface that inserts into the black ABS plastic sink and floor couplings was too soft to allow for a secure fastening of the hose to the sink and floor plumbing. The solution we have now provides a metal insert that can be securely clamped to the more flexible white hose. While the reducer nut and its red oversized washer are less than ideal (IMO) this is the function they were designed to serve. So, we've got a much more flexible hose that is replaceable and a much more secure fastening system.
