3/4" RV Sewer Cap - Universal Leak-Proof Waste Tank Cap for RV, Trailer & Camper, Easy Drain Design Replacement Sewer Hose Cap (Black)

Ensure a clean and hassle-free RV experience with our 3/4" RV Sewer Cap, the ultimate leak-prevention solution for your waste management system. Designed for reliability and ease of use, this cap features a secure bayonet lock mechanism that clicks firmly into place with a simple push and turn. This creates a watertight seal, effectively preventing messy leaks and containing odors, whether you're on the road or parked at the campsite.

• 【Upgrade to Leak-Proof Security】 Stop worrying about nasty spills and unpleasant odors during transit. The JIYIZO RV sewer cap features a heavy-duty sealing gasket and a secure bayonet lock that creates a 100% airtight seal. Unlike stock caps that crack or loosen, our cap stays firmly in place, ensuring no wastewater leaks onto your campsite or storage compartment.
• 【Easy Drain & Flush Design (Built-in Hose Adapter)】 Tired of getting sprayed by residual water when removing the cap? This upgraded cap features a standard garden hose thread (GHT) outlet. Simply attach your hose to direct any residual "surprise" water safely into a bucket or the dump station. It also doubles as a convenient flush port for rinsing your black tank.
• 【Heavy-Duty & Weather-Resistant Construction】 Built to outlast the original factory caps, the JIYIZO sewer cap is molded from high-impact ABS plastic with UV inhibitors. It won't warp under the blazing sun or become brittle in freezing winter conditions. The textured grip allows for easy twisting on and off, even when wearing gloves.
• 【Universal 3" Bayonet Fit for Most RVs】 Specifically designed to fit standard 3-inch bayonet sewer connections. Perfect for travel trailers, 5th wheels, campers, pop-ups, and motorhomes. Whether you own a Winnebago, Forest River, or Grand Design, this cap is a direct replacement for your lost or damaged stock cap. (Please check your RV outlet size before ordering).
• 【Convenient Tether & Space-Saving Design】 Includes a sturdy retaining tether to prevent losing the cap at the dump station. The compact, low-profile design also fits perfectly inside your RV's rear bumper storage tube without getting stuck, keeping your sewer hose accessories organized.
