I use them with the Kiinde Spectra adaptors and it's off just a little, but still works. **Q: Are these compatible with the Hygeia Fit breast pump?** A: I’m not sure. These are compatible with Spectra parts so if your pump works with Spectra too then these would work for sure. ## Customer Reviews ### ⭐⭐⭐⭐⭐ We Used Them *by B***X on August 14, 2026* You know what they're for. They work. ### ⭐⭐⭐⭐⭐ Spectra replacement *by N***U on August 2, 2025* Exactly what I needed for my spectra pump. Fit perfectly ### ⭐⭐⭐⭐⭐ Perfect Replacement for Spectra Lhmp *by K***. on June 15, 2025* Work great as replacement parts for my Spectra pump. I needed an extra pair of flanges and these got the job done. They are hard plastic, can be put in the dishwasher, and the only real difference I can see from the set that came with the pump is the neck is a bit longer. Additionally, sometimes you have to unscrew and screw it a couple times before it lines up properly with the bottle. These were a great buy and I would purchase them again if I needed too. ## Frequently Bought Together - Nenesupply 21mm Flanges 2pc Compatible with Spectra S1 S2 Synergy Gold Motif Luna Breastpumps Replacement to Spectra Pump Parts and Flange 21mm Replace S2 Parts and Accessories - PUMPMOM-US Replacement Duckbill Valves and Backflow Protector for Spectra, Compatible Pump Parts for Spectra S1 S2 9 Plus and SG (Not Original S2 Accessories) - Momcozy Hands Free Pumping Bra, Adjustable Breast-Pumps Holding and Nursing Bra, Pumping & Nursing Bra in One --- ## 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.sc/products/215335917-21mm-flanges-2pc-compatible-with-spectra-s1-s2-synergy-gold](https://www.desertcart.sc/products/215335917-21mm-flanges-2pc-compatible-with-spectra-s1-s2-synergy-gold) --- *Product available on Desertcart Seychelles* *Store origin: SC* *Last updated: 2026-10-08*
