Compare RV sewer hose Y connectors, wye fittings and extension hoses, including AVERONR 6-in-1, Tlaleikejia, DUMPMAN and Camco twist connect kits.

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

A Y connector, or wye, lets two sewer hoses feed one dump inlet, which helps when you carry two tanks or two hoses. The details that matter are swivel ends, gaskets and which inlet sizes the fitting accepts.

Six products are compared, including three wye fittings, a twist connect kit, an extension hose and an inlet adapter. Match each listing's stated sizes to your own inlet.

Before you buy

What Matters Before You Choose an RV Sewer Hose Y Connector

Key buying criteria so you get the right fit the first time.

01
Two-hose need
A wye suits two hoses or tanks. One hose does not need it. Count your hoses.
02
Inlet sizes
Wyes fit named inlet sizes. Check 3, 3.5 and 4 inch NPT and slip. In rv sewer hose y connector, note inlet sizes first.
03
Swivel ends
Swivel ends ease alignment. Look for 360 degree language. Across rv sewer hose y connector, read swivel ends closely.
04
Gaskets
Gaskets stop leaks and smell. Check for built-in gaskets. With rv sewer hose y connector, find gaskets stated.
05
Clear body
A clear piece shows drain status. Check for transparent. On rv sewer hose y connector, confirm clear body directly.
06
Joiner versus Y
A twist kit joins in line, not at a Y. Check the product type. In rv sewer hose y connector, note joiner versus Y first.
