Camco Mfg 39313 Rv Sewer Hose Ring Seal 4x3 in 3-pack

Product Description

The CAMCO MFG 39313 is a sponge ring seal designed to create a watertight connection between an RV sewer hose and a dump station or campsite sewer inlet. Measuring 4 inches outer diameter by 3 inches inner diameter, this seal compresses around the hose to block odors and prevent leakage at the point of connection. Each package includes 3 seals, making it a practical supply to keep on hand for routine maintenance or replacement. The sponge construction conforms to irregular fitting surfaces for a reliable field seal without tools.

This seal is used in recreational vehicle wastewater service. It fits between the RV sewer hose outlet and the dump station inlet collar, providing a barrier against sewer gas and spillage during tank emptying. Typical users include RV service technicians, campground maintenance crews, and experienced RV owners performing their own sanitation service. The 3-pack format supports fleets, rental units, or technicians who service multiple vehicles.

Installation Notes

Sanitation system work on RVs should follow standard wastewater handling precautions, including use of appropriate personal protective equipment. Close all tank valves before disconnecting the sewer hose. Slide the seal onto the hose end so it seats flush against the dump station inlet collar before opening the tank valve. Inspect the seal before each use and replace if the sponge shows compression set, tearing, or deterioration.
