วาล์วปากเป็ด ชุด 4 ชิ้น (สำหรับกรวยปั๊มเท่านั้น)

The one-piece construction actually holds up well to daily use and cleaning, and the pull tab makes swapping them out quick. I’ve been using them for a couple weeks now without any leaks, which is a big improvement over my old valves.

These pull tabs are a lifesaver when my hands are wet and slippery after washing bottles. They fit my flanges so snugly that I haven't had a single leak since switching, and the one-piece design makes cleaning a breeze.
