6 Best RV Sewer Hose Bayonet Fitting in 2026: A Practical RV Guide

Compare RV sewer hose bayonet fittings, rotating adapters and storage caps, from TonGass and Valterra rigid adapters to Camco bayonet and elbow caps.

By Bowen HigginsRV Editor at RV Gear Lab6 products comparedSpec-sheet researched

A bayonet fitting is the twist-and-lock end that joins a sewer hose to an RV outlet, a cap or an adapter. The pieces vary by thread, rotation and whether they are meant to join, adapt or cap an end.

Six bayonet products are compared, including rotating rigid adapters, an EZ coupler and two caps. Check each listing's thread type and the other end's size so the parts actually mate.
