Create a secure, gas-tight connection at the dump station with the Valterra F02-4600 Soft Sewer Sponge Ring. Made from durable, compressible sponge material, this sewer seal helps prevent sewer gases and odors from escaping by creating a tight seal between your RV sewer hose fitting and the campground sewer inlet.
Designed to fit 4-inch x 3-inch sewer fittings and sewer hookups up to 4.5 inches in diameter, this sponge ring is compatible with most RV drain hoses and sewer fittings. Simply place the ring around the sewer connection to improve the seal and help keep your dumping experience cleaner and more sanitary.
Compact, lightweight, and easy to use, the Valterra Soft Sewer Sponge Ring is an essential accessory for RV owners, campers, and travel trailer enthusiasts.
