What pumps and bottles does this bottle thread converter adapter work with?

This bottle thread converter adapter works with Spectra S1, Spectra S2, and Spectra 9+ wide-mouth flanges, as well as compatible Maymom wide parts. It connects those pump parts to wide-neck bottles from Lansinoh, MAM, Pigeon, and Evenflo. It is designed for parents who pump with Spectra parts but prefer feeding or storing milk in those specific bottle brands.

How does the leak-free design help prevent milk spills?

The adapter uses precision-engineered threads and a snug silicone seal so the connection between the pump flange and bottle stays tight. This design reduces the chance of leaks, drips, or loose fittings and helps keep breast milk in the bottle instead of on your counter or pump parts.

What materials are these adapters made from, and are they safe for babies?

These adapters are made from BPA-free, food-grade plastic that is safe for contact with breast milk. The material is durable, heat-resistant, and compatible with common sterilizing methods, which helps parents maintain a clean and safe pumping setup for their baby.

How many adapters come in a pack, and how should I use them?

Each package includes a 4-pack of adapters. Many parents keep some at home and others in a pump bag or at work so they always have a converter ready. To use, attach the adapter to your Spectra wide-mouth flange, then twist your Lansinoh, MAM, Pigeon, or Evenflo wide bottle onto the adapter and start pumping.

How do I clean and care for these bottle thread adapters?

You can wash the adapters in warm, soapy water and rinse them well, or you can sterilize them along with your other pump parts using your usual method. The heat-resistant, food-grade plastic holds up to regular cleaning, which supports a hygienic pumping routine.
