The CAMCO MFG 39163 is an internal sewer hose coupler designed to connect two RV sewer hoses end-to-end with a quick, secure, airtight seal. Tapered ends slide into standard 3-inch sewer hoses, accommodating both slip-over and direct-fit configurations. The non-restrictive interior bore maintains free flow throughout the connection, preventing backpressure or blockage at the joint. Each package includes 2 couplers. The compact profile is sized to store inside a standard 4-inch RV bumper alongside the hose itself, keeping the connection hardware with the hose at all times. This part is typically installed by RV owners, RV technicians, or campground maintenance staff.
This coupler is used in residential RV and travel trailer sewer systems where two sewer hose sections must be joined for extended reach. The tapered slip-fit design requires no tools and works with the full range of standard 3-inch RV sewer hose diameters available in the market. The airtight connection limits odor escape at the joint during dump station use. Its ability to store inside a 4-inch bumper makes it a compact, practical addition to any RV sewer hose kit.
Designed as a replacement or supplemental coupler compatible with standard 3-inch RV sewer hoses and slip-over fittings, suitable for storage in standard 4-inch RV bumpers.
Installation requires no tools — slide each tapered end into the open ends of two sewer hose sections until seated. Ensure the hose connections are fully seated on both tapered ends before use to maintain the airtight seal. Always wear appropriate personal protective equipment when handling sewer hose assemblies. Disconnect and flush hoses thoroughly before storage.
