What it does
- Attaches to your RV hose without over-threading so you can fill your tank hands-free
- Keeps your hose kink-free during fill-ups, so water flows smoothly every time
- Designed for travel trailers and camping setups, making de-winterizing faster
- Printed on demand from the US, so you get a coupler made just for your order
Fill your RV freshwater tank without wrestling with hose connections. This coupler lets you attach and detach smoothly, keeping your hose straight so you can focus on the job at hand.
The design solves a real problem. Standard couplers spin freely once over-threaded, but this one stays put. You get a secure fit that does not kink your hose during the fill-up process. Works great for spring de-winterizing when you need things to go smoothly.
Designed by an RV owner for travel trailers and camping rigs. Since hose sizes vary, check the design notes if you are unsure about fit. Your feedback helps improve the design for everyone.
