The CAMCO MFG 39403 is a 45-degree RV sewer hose adapter fitting sold in a 2-pack. It is designed to redirect a sewer hose connection at a 45-degree angle, reducing stress on the hose and improving the connection angle between an RV sewer outlet and a campground or dump station inlet. The angled design helps create a more secure, leak-resistant hookup in tight or awkward drain positions. Each unit weighs approximately 0.5 pounds. This fitting is a standard accessory for RV waste system service and maintenance.
This adapter is used in RV sanitation systems where a straight connection creates an awkward hose run or places strain on the sewer outlet fitting. It is well-suited for use at campgrounds, RV parks, and dump stations where drain inlet placement does not align cleanly with the RV sewer outlet. RV service technicians and owner-operators alike use this fitting to simplify waste hose routing and maintain a secure connection during dump procedures.
Designed as an OEM-style replacement and accessory fitting compatible with standard RV sewer hose systems.
This fitting is typically installed by RV technicians or owner-operators as part of routine waste system hookup. Before connecting or disconnecting sewer fittings, ensure all tank valves are fully closed to prevent discharge. Standard RV sewer hose fittings use a twist-lock or bayonet-style connection — inspect the adapter and hose fittings for wear or cracks before each use. Follow applicable campground or dump station guidelines for waste handling procedures.
