F02-4600 is a soft sponge sewer seal ring by Valterra, designed to create a gas-tight connection between an RV sewer hose or fitting and a campground sewer inlet. Measuring 4" x 3", this flexible seal helps reduce escaping sewer gases and unpleasant odors during waste disposal. It is useful at RV parks and campgrounds where a sealed sewer connection is required. Check the dimensions of your sewer inlet and fittings before use.
