Great prices and fast shipping on genuine Spectra breast pump replacement parts and accessories for the Spectra S1, Spectra S2, S3 PRO, Spectra Synergy Gold and Spectra 9 Plus breast pumps. Spectra replacement parts in stock for immediate shipping including the Spectra BPA Free Double Collection Accessory Kit for your convenience! 
We offer five breast flange size options for your perfect Spectra breast flange sizing with a comfortable effective fit as well as Spectra duckbill valves, Spectra backflow protectors and tubing. 
Orders placed before 2pm CST weekdays ship out same day.


Spectra breast pumps and replacement parts are safe and hygienic – all pumps include the backflow protectors, to prevent milk travelling down the Spectra tubing towards the pump to prevent a hygiene risk for mold, transmission of viruses and potentially impairing motor function. Spectra breast pump parts that come in touch with milk are all BPA-free. Spectra breast pumps are innovative & practical – with features that women need, like double-sided expressing capability and adjustable cycle length. Lactation Connection specializes in Spectra S1 S2 and Synergy Gold replacement parts and offers commonly replaced parts for the Spectra S1, Spectra S2, Spectra Synergy Gold and Spectra 9 breast pumps such as the Spectra duckbill valves, backflow protector filter, and tubing as well as the full Spectra Universal Double Collection Accessory Kit in 20mm, 24mm, and 28mm breast shield sizes. Lactation Connection also offers Spectra bottles and genuine Spectra Anti-Colic Slow Flow Bottle Nipples - 2 Pack .

Spectra Baby USA is a trusted name in the breastfeeding world, offering hospital-grade and personal-use breast pumps, along with a complete line of replacement parts and accessories. Designed by moms and lactation consultants, Spectra pumps provide comfortable, quiet, and efficient pumping to support your breastfeeding journey from day one. Whether you're a new mom or upgrading your current pump, Spectra offers advanced features, closed-system hygiene, and customizable settings to suit your needs. Popular models include the Spectra S1, S2, 9 Plus, and Synergy Gold, each compatible with genuine Spectra accessories for a seamless pumping experience.

Spectra Breast Pump Parts & Accessories

Using authentic Spectra parts ensures compatibility, hygiene, and peak performance. Replace parts regularly to maintain suction strength and protect milk quality.

1. Spectra Flanges (Breast Shields)
Available in sizes 16mm, 20mm, 24mm, 28mm, and 32mm for optimal comfort and milk output. A proper fit prevents nipple pain and improves pumping results.

2. Spectra Duckbill Valves
These regulate milk flow and suction strength. Replace every few months as elasticity wears down.

3. Spectra Backflow Protectors
Essential to the closed system, these protect the tubing and motor from milk contamination.

4. Spectra Tubing
BPA-free, clear tubing that connects pump to flanges. Necessary for double-pumping and should be replaced periodically.

5. Spectra Bottles & Milk Storage
BPA-free bottles with secure lids. Safe for refrigeration and freezing. Compatible with all Spectra pumps.


Why Moms Love Spectra
Spectra Baby USA leads in innovation, performance, and safety—offering hospital-strength pumps, hygienic accessories, and customizable features that support both exclusive pumping and combo feeding.

Whether you're building a stash, returning to work, or pumping exclusively, Spectra products help you pump comfortably, efficiently, and safely—from first latch to final session.
