T1020-1 is a Valterra 3-inch RV sewer termination cap designed to seal compatible waste outlet connections. Its bayonet-style mounting provides a twist-on connection, while the integrated 3/4-inch garden hose connector allows a hose to be attached for suitable draining or flushing applications. The cap is made of black plastic and includes a seal to help prevent leaks. Check your outlet type and connection size before installation.
