Trymall Flange Inserts 13/15/17/19/21mm for Medela/Spectra – 5pc Pack

Find Your Perfect Fit

Choosing the right flange insert size can influence both comfort and pumping consistency. The Trymall 5-piece set includes 13, 15, 17, 19, and 21 mm inserts, designed to work with popular 24 mm shields from Medela and Spectra, among others. This pack invites you to explore multiple sizes to discover the best match without guessing.

Made from BPA-free, food-grade silicone, these inserts are soft and flexible, with smooth edges that glide against the skin. Their gentle composition aims to support a steady pumping rhythm while reducing overall pressure on sensitive areas during use.

What you get

• Five sizes: 13, 15, 17, 19, 21 mm, packaged as a single 5-piece set
• Broad compatibility with Medela PersonalFit 24 mm shields, Spectra 24 mm flanges, and many wearable pumps like Momcozy S9/S12
• Designed to fit 24 mm shields and help bring the tunnel closer to size (not compatible with 27 mm shields)
• BPA-free, food-grade silicone; easy to rinse and sanitize

Real-life use and benefits

Use the inserts to tailor the feel during pumping, especially if you notice mild swelling or a tight tunnel with a 24 mm shield. Observe nipple shape during pumping and swap sizes every 1–2 months to maintain comfort and fit. The compact, 5-piece pack fits neatly in a drawer or bag for quick sizing on the go.

Care and maintenance

• Rinse after use; wash with mild soap; air dry fully before storage
• Inspect for wear and replace regularly to keep performance consistent

Compatibility notes

These inserts are designed for a broad range of brands and wearable pumps. Before use, confirm your shield diameter and connector compatibility. Not all 24 mm kits share the same connector, so verify fit with your system.
