RV owners know the frustration of sewer hose connections that leak, drip, or allow foul odors to escape. Standard rubber gaskets dry out and crack, while makeshift solutions fail under pressure. The Lippert Soft Sewer Sponge Ring solves these problems with its specially formulated foam that compresses to form a perfect seal around your 3" waste outlet.
Features & Benefits
- 4" outer diameter with 3" inner diameter fits standard RV waste outlets
- High-density foam compresses to create an airtight seal that prevents leaks
- Odor-resistant material won't absorb smells like rubber gaskets
- Durable construction maintains flexibility in all weather conditions
- Easy installation - simply slide between tank flange and sewer hose
- Reusable design lasts longer than disposable alternatives
Unlike rigid rubber gaskets that crack over time, this sponge ring's flexible foam adapts to slight variations in connection points. The material stays pliable in both freezing winter temperatures and scorching summer heat, ensuring reliable performance year-round.
Every RV owner needs this simple but critical component. Without a proper seal, you risk messy leaks during dumping and persistent sewer gas odors in your living space. The Lippert Soft Sewer Sponge Ring provides peace of mind with its OEM-quality construction and proven leak prevention.
