The CAMCO MFG 39173 is a straight sewer hose adapter designed for RV waste system connections. It features tapered ends that accept standard 3-inch sewer hoses and creates an airtight, odor-free seal between the hose and the RV sewer outlet. The adapter is built for non-restrictive flow, meaning it does not reduce the internal diameter of the hose line during operation. Each package contains two adapters. RV service technicians and self-maintaining RV owners install this part when setting up or replacing sewer hose connections at the coach. Its compact profile allows it to store directly with the hose inside a standard 4-inch RV bumper.
This adapter is suited for residential and travel trailer RV sewer systems where a straight inline connection is needed between the coach outlet and the dump hose. The tapered design makes it compatible with all standard 3-inch RV sewer hoses, which is the industry-standard diameter for this application. It is commonly used at campsite hookups and during dump station service. The airtight slip fit reduces odor bleed at the connection point, which is a common complaint with loose or worn adapters.
Designed as an OEM-style replacement or spare for RV sewer systems using standard 3-inch diameter sewer hoses and 4-inch bumper storage.
Installation is handled by the RV owner or an RV service technician and requires no tools for a standard slip-fit connection. Before connecting or disconnecting the sewer hose, ensure the coach holding tank valves are fully closed to prevent discharge. Inspect the tapered ends for cracks or deformation before each use, as a damaged adapter will compromise the odor seal. Follow all campground and local sanitation regulations when working with RV waste system components.
