The product description says yes, but the picture says no.** A: If you have a medela flange and want to use it with S2 pump, buy this backflow protector. If you have an original spectra flange, this backflow protector will not fit it, but it can still fit the tubing end that come from the pump main unit. **Q: Can i use medela tubing with this or would i need to purchase spectra's tubing?** A: HI, you can use medela pump in style tubing with this one as long as you cut off the tubing adapter on the tubing. it is tight fit, but it will work. **Q: Does this work with spectra M1?** A: The short end can attach to the tubing from M1, but the long end will need to connect to a Maymom or Medela flange, not a spectra widemouth flange. ## Frequently Bought Together - Maymom Backflow Protector, Long Stem, Compatible with Spectra S1, S2 and 9 Pumps, Compatible with Medela Flanges and Medela Parts; 2pc - Maymom MyFit Narrow Neck Base Connectors; Compatible with Medela PersonalFit Connector; Use w/Maymom Two-Piece Shield System, Compatible with Medela Freestyle Flex BreastShield; Lansinoh Shields; 2pc - Legendairy Milk Duckbill Valves with Pull Tab - Compatible with Spectra - Pack of 6 --- ## 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.co.uk/products/26643503-maymom-backflow-protector-long-stem-compatible-with-spectra-s1-s2](https://www.desertcart.co.uk/products/26643503-maymom-backflow-protector-long-stem-compatible-with-spectra-s1-s2) --- *Product available on Desertcart United Kingdom* *Store origin: GB* *Last updated: 2026-07-26*
