Spectra Sizing Options (Flanges and Inserts)
The Spectra is my number one choice of pump for daily pumping use. It is durable, works with many sizes of nipples, and has a wide-array of fitting after-market brands that make this pump a go-to for pumping parents everywhere.
The purpose of this blog post is to give readers direct links to the Spectra pumps, on-brand and after-market flanges and inserts based on their measured nipple size.
Because this blog post is VERY long with many different sizing options, it may be faster for you to see your best options using a non-mobile device. If you are still frustrated with trying to find what will work for you, don’t hesitate to schedule a professional sizing.
Happy Pumping :)
Spectra Pumps
The Spectra S1 is my favorite Spectra Pump, and very close to my favorite overall pump. This pump is portable, with a rechargeable battery. It’s a strong and durable pump with a reputation for holding up to the needs of frequent pumpers. This pump allows control of the Cycle Speed and the Suction Strength.
The Spectra S2 is the non-battery operated version of the Spectra S1.. It’s a strong and durable pump with a reputation for holding up to the needs of frequent pumpers. This pump allows control of the Cycle Speed and the Suction Strength.
The Spectra S9 is a rechargeable battery operated portable pump. This pump does not perform with the same strength and reliability we saw with the S1 and S2. It is not intended for frequent or heavy use. Compared to other portable pump options this pump falls short with size and features.
The Synergy Gold is the newer Spectra Pump that allows independent suction control for each breast. This pump does not have a rechargeable battery.
The Dual Compact is the latest Spectra Model and is not yet available for sale in the United States. It is being imported by parents though, and is the portable and rechargeable version of the Synergy Gold.

Hard Plastic Flanges with Silicone Inserts
Silicone inserts were originally designed for 25 mm and 28 mm Freemie Cup Flanges, but they can be used with standard hard plastic flanges. They fit in many brands of flanges, but some flanges less than 25 mm may NOT allow the inserts to fit flush because of the flange angles.
