Willow Wave Gaskets (2-pack)

Two sets means I've got a backup ready when I'm scrambling to pack for work trips, and the seal itself feels snug against the flange right out of the box. The pump held steady without any leaking mid-session, which is all I really wanted.

The seal on my pump was getting unreliable after a few months, and swapping in one of these made a world of difference—no more leaks during my morning sessions. The two-pack is a smart buy since I always keep a spare in my bag, and the fit is perfectly snug against the flange.

These replacement gaskets fit into my pump without any fuss, and the seal feels just as solid as the original. I grabbed the 2-pack so I always have a fresh one ready in my bag for when the current one starts to wear.
