eufy 유축기 S2 / S2 Pro용 이중 밀봉 플랜지 (27mm)

The fit is noticeably snugger than the stock flanges, and that double-sealed rim means zero leaks even when I bend over to grab the pump bag. I've used it three times now and it clicks in perfectly every time, no fiddling.

I was a little nervous the 27 mm size wouldn't feel right, but the double-sealed design clicks into place so snugly that there’s zero wobble while I’m pumping. It’s made my S2 Pro sessions noticeably quieter and more comfortable than with the standard parts I had before.

The seal holds so firmly that I stopped worrying about leaks mid-pump, and it clicks into place with my S2 Pro without any fiddling. Honestly, the peace of mind alone is worth it for how secure this feels.
