Valterra swivel bayonet fitting: replacing a cracked bayonet instead of the whole hose
A rotating bayonet the listing describes as the connector between a sewer hose and the RV waste valve. The page does not print a diameter. Confirm it is the standard 3-inch RV bayonet before you order.

7.2/10 RigRank score
When a hose leaks at the RV, the hose wall is often fine and the bayonet is not. A cracked lug, a flattened gasket, or a fitting that was side-loaded because the hose was too short will drip on the first valve you open. Replacing the fitting is the repair. Replacing a 20-foot hose because the plastic end split is how people spend more than they need to.
This Valterra listing was in stock and describes a quick-connect rotating bayonet for the sewer waste valve. What it does not do, in the text we could read, is print '3 inch' in a specification table. RV sewer hose fittings are a de facto standard, and a water-hose fitting is not that standard. Read the photos and the questions on the listing and match the lugs to the fitting in your hand. If you are unsure, buy the fitting from the same brand as the hose.
A swivel is the feature worth paying for. A fixed bayonet forces the hose to leave the outlet at whatever angle the lugs landed. That twist becomes a side load, and side load is what cracks the next fitting. The length calculator's slack exists so this part is not asked to bend.
What the listing actually says

Works in its favor
- The right category of spare: the end that actually breaks
- Listing says the fitting rotates
- Cheaper experiment than a new hose kit if the wall is sound
Holds it back
- Diameter is not clearly printed on the listing text we verified
- A new fitting on a cut, crushed hose does not fix the hose
- Gasket quality is the whole seal, and listings rarely show the gasket well
Which listing to open
- Valterra swivel bayonet B01KR7DEQC on Amazon
Questions worth answering first
Should I replace the hose or the fitting?
If the drip is at the lug and the hose wall is flexible, round, and not pinholed, replace the fitting and the gasket. If the wire is crushed, the wall is cracked, or the hose is stiff and chalky, replace the hose. The leak article walks through that split.
