This black plastic cap seals your RV’s waste tank vent when the system isn’t in use or during storage. Designed to thread onto the vent outlet, it prevents rain, snow, and debris from entering the vent stack while parked. The included stainless steel hardware ensures corrosion resistance on the coast or in wet climates.

Quick to install and remove—no tools required beyond hand-tightening. Light weight won’t stress your roof or vent assembly. Fits the JR Products hatch installation kit (P/N 04195).
