It depends on your connection with the pipe if you need a spigot to spigot or hub to hub valve. A hub connection is the female connection that accepts a spigot. The spigot is a male connection. If your existing valve slides into the 3" pipe then you need the spigot connection.

The Valterra Bladex Waste Valve for RV Black Water Tank - 3" Spigot to 3" Spigot part # T40A is designed to slide into 2 separate 3" sewer pipes which sounds like what you have. You will need Valterra ABS Solvent Cement part # A05-0303 to seal it.

If your valve attaches to the outside of the pipe, you need a hub style connection Valterra Bladex Waste Valve for RV Black Water Tank part # T40B. You will still need the solvent to install it.

The difference between hubs and spigots in terms of RV waste valves like the part #T40A is that hubs fit over pipes and spigots fit into them instead. So it really comes down to if you have a preference but the #T40A is a spigot on both sides.
