- Washing machine pan gap packing - Material: Elastomer - Size: 37mm - Length: 640mm Thank you for viewing. I purchased two of these to use on one side and the back of a top-loading washing machine. I opened one and tried to fit it, but I'm not very good at it, so I couldn't do it properly and put it away. There are creases, probably from when it was shipped, but I think it will be fine once installed. Please understand this. One is unopened, and the other is without a bag.
