Trymall Flange Inserts 13/15/17/18/19/20/21mm – 14pcs, 24mm Shield Compatibility

Find Your Perfect Fit with Trymall Flange Inserts

Meet the Trymall Flange Inserts—a 14-piece set designed to tailor the fit of 24mm shields across a broad range of popular breast pumps. The kit includes seven sizes (13, 15, 17, 18, 19, 20, 21 mm), with two inserts per size, giving you the flexibility to fine-tune comfort without replacing your shield collection.

Why this set matters

Comfort during pumping depends as much on fit as on suction. The inserts are made from transparent silicone and are BPA-free, offering a clear view of how well they sit against the skin while you pump. With seven sizes and two inserts per size, you can adapt to changes in size over time or across different pumping sessions, helping you explore what feels best without committing to a single option.

• Seven sizes in one set: 13–21 mm, two inserts per size for rapid adjustments.
• Wide shield compatibility: designed for most 24mm shields from major brands; not compatible with 27mm shields.
• Cost and time savings: reduces the need to test multiple shields and sizes.

Real-life use cases

• A busy morning session: swap to a snugger size for a secure seal and steadier suction during a shorter pump.
• During lactation changes: if size shifts, simply switch inserts instead of buying new shields.
• Travel-friendly: carry the 14-piece set to adapt to different pumping environments with ease.

Materials and safety

• Transparent silicone construction and BPA-free composition support daily use.
• Easy to keep clean; a quick rinse helps preserve clarity and comfort.

Usage tips and compatibility

• Designed for 24mm shields/shields; not suitable for 27mm shields.
• For smoother application, some users apply a light amount of coconut oil or nipple butter to reduce friction.
