I needed them to protect my sterilizer's UV light from my PEX piping system. I turned them into a loop between the sterilizer and the PEX tubes and no more light entered my PEX tube. (By comparison, a straight length of white PEX tubing coming out of a sterilizer will illuminate the tubing in the dark with a nice purple hue.) I was a little concerned that the rubber gasket on washer might leak, but no problem. Hope the pucks last a long time.
