How to Choose a Flange Insert

A few quick checks will help you pick the right insert size and avoid common fit mistakes.

  1. Check your current fit: If your nipple rubs the tunnel edges or there is lots of areola in the tunnel, try a smaller insert.
  2. Measure for reference: Measure your nipple diameter at rest and after a short pump to guide your size choice.
  3. Start one size down: If your flange feels too large, try one insert size smaller rather than jumping several sizes.
  4. Watch for signs: Comfort, reduced rubbing, and steady milk flow show a good fit. Pain or pinching means size up.
  5. Try before you commit: Inserts are a low-cost way to test a smaller effective size without replacing your whole flange set.
Frequently Asked Questions
Will these inserts fit my pump?

They are designed to resize most regular 24 to 25mm flanges, but not all wearable-specific funnels. If your flange measures 24 to 25mm across the opening, these inserts will usually seat inside the tunnel, creating a smaller effective size.

How do I choose the right insert size?

Start by assessing how much areola sits in the tunnel and whether the nipple rubs the sides. If the flange is too large, try one size down and compare comfort and milk flow.

How do I clean and care for the inserts?

Wash with warm soapy water and rinse well after each use, or follow your pump manufacturer guidance for compatible silicone parts. Inspect regularly for wear and replace if damaged.

Can inserts help with sore nipples?

Yes, many moms find that a better fit reduces friction and keeps the nipple centered, which can lower soreness and prevent rubbing-related issues.
