17mm MyFit Crater Shape Flange- 2 pack

The MyFit Crater Shape Breast Shield is a replacement breast pump flange designed to improve pumping comfort, fit, and milk flow. More than just size matters — flange shape can also affect comfort and how breast tissue and the nipple move during pumping.

The Crater Shape design is created to gently hug the breast tissue while helping stabilize the nipple within the flange tunnel. Some parents find that different flange shapes can improve comfort, create a better seal, and support a more efficient pumping experience.

Created by Maymom, these hard plastic flanges provide a precise tunnel diameter to help parents achieve a personalized fit and more effective pumping sessions.

Features:
• 17mm Hard plastic breast shield/flange design
• Crater-shaped contour designed to hug breast tissue
• Helps stabilize nipple positioning within the tunnel
• May improve comfort and pumping efficiency
• Available sizes: 12mm, 13mm, 14mm, 16mm, 17mm, 18mm, 20mm
• BPA-free materials
• Steam sterilization safe
• Easy to assemble and clean
• Each package includes 2 breast shields/flanges

Please note: You'll need a connector!
All available at The Pump Bar:

Finding your ideal flange fit isn't just about diameter. Shape matters too. MyFit options like Conical, Crater, Pano, Comfy, and Saucer offer different contours to help support your unique anatomy and pumping goals.
