Would recommend! ### ⭐⭐⭐⭐⭐ Perfect Flange *by on Reviewed in the United States July 9, 2024* These fit into my Elvie stride perfectly.

They do the job and they’re comfy though. ## Frequently Bought Together - Nenesupply 21mm Flange Insert Compatible with Elvie Flange Pump Parts Elvie Stride Flange Momcozy Medela Flange Spectra Willow Reduce 24mm to 21mm Use as Elvie Inserts Medela Insert Momcozy Insert - Nenesupply 4pc Duckbill Valves Compatible with Elvie Stride Pump Parts Replacement Parts Breast Pump Parts Momcozy Tsrete Wearable Pumps Spectra CaraCup Not Original Elvie Pump Parts Accessories --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.sn/products/380338820-nenesupply-21mm-flange-insert-compatible-with-elvie-stride-flange-pump](https://www.desertcart.sn/products/380338820-nenesupply-21mm-flange-insert-compatible-with-elvie-stride-flange-pump) --- *Product available on Desertcart Senegal* *Store origin: SN* *Last updated: 2026-07-13*
