I’m not familiar with the Spectra but I think these would probably universally fit most 24mm flanges. These have been great quality flange inserts and I’ve been very happy with them. ## Frequently Bought Together - 5Pack Silicone Duckbill Valve & 4Pack Silicone Diaphragm Compatible with momcozy S9 / S12 / S9Pro / S12Pro Wearable Breastpump, Breast Pump Replacement Parts, Breastfeeding Essential Accessories - Momcozy Original S9 Pro/S12 Pro Replacement Accessories, Only Compatible with Momcozy S9 Pro/S12 Pro Breast Pump NOT for S9/S12 (Single-Sealed Full Set Collector Cup with 24mm Flange,180ml, 1 Pack) - Momcozy Flange Insert 21mm Compatible with 24mm Flange/Shield of Most Pumps, Insert for Breast Pump Replacement Accessories, 4PCS 21mm --- ## 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.com.ar/products/720681850-6-pack-silicone-duckbill-valve-and-4-pack-silicone-diaphragm](https://www.desertcart.com.ar/products/720681850-6-pack-silicone-duckbill-valve-and-4-pack-silicone-diaphragm) --- *Product available on Desertcart Argentina* *Store origin: AR* *Last updated: 2026-07-06*
