Portable Breast Pump Drain Plug

Breast Pump Drain Hole Plugs – A Simple Fix for Unexpected Spills

I designed these drain hole plugs to solve a frustrating (and messy) issue my wife kept running into while pumping. She’d lean forward just a bit too far—and suddenly, breast milk would spill out of the drain slots and soak her shirt. Not exactly the kind of surprise you need in your day!

These plugs fit right into the drain slots of the breast milk containers to help prevent that kind of mess. While they don’t form a completely watertight seal (due to the way the silicone cover rests), they’re great at stopping a sudden stream from leaking out and making a mess.

They're quick to insert, easy to remove, and can make pumping a little more stress-free.
We use the plug on this pump we got from Amazon.

Material Used for Model:
Overture TPU - Grey

You can try other materials, but I think TPU works best, if you need to scale it up a tiny bit for a more snug fit.
 

✅ Compatible with the following pump bands/models:

Sometimes the smallest fixes make the biggest difference—I hope these help you avoid the same spills we did!
