Valterra T1006 RV 3″ Spigot FlangeThe Valterra T1006 RV 3″ Spigot Flange is a durable sewer valve fitting designed to connect a 3-inch sewer pipe to an RV black-water waste valve. The spigot end slides directly into a 3-inch sewer pipe and is secured using ABS solvent cement, while the integrated flange bolts onto the waste valve to create a strong, leak-resistant connection.
