Spectra Breast Shield Flange Sizes 20MM 24MM 28MM 32MM

Not only is getting the right breast pump important, but so is getting the right breast shield flange size.  If you pump regularly, using the correct breast shield size aids in adequate milk production.  With the increasing popularity of Spectra breast pump, we want moms to have the information as to what sizes are available and how you can purchase them.

Spectra Standard Breast Shield - 24mm
The 24mm breast flange was included with your Spectra breast pump including the S1 and Spectra S2 breast pump.  If you are pumping comfortably with this flange and there is room on one side of the flange shaft for freedom of movement, the standard size works for you.  The Spectra 24MM breast shield can be purchased in the following ways:

Spectra 24MM Breast Shield - Single (breast shield only)
Spectra 24MM Breast Shield Set - includes breast shield, valve, tubing and backflow protector
Spectra 24MM Premium Accessory Kit - breast shield, valve, tubing, backflow protector, bottle set
Spectra 24MM Double Pump Kit - 2 breast shields, 2 valves, 2 tubing, 2 backflow protector, 2 bottles

Spectra Small Breast Shield -20mm
The 20mm breast flange is a good choice if you are pumping with the standard 24mm flange and there is room on all side of the flange shaft.  You may experience too much of the areola being drawn into the shaft as not to receive adequate compression of the milk sinuses if your flange is too large.  Another reason you may need the small Spectra flange is too much elasticity in the nipple causing the nipple to draw too far into a standard flange.  The Spectra 20MM breast shield can be purchased in the following ways:

Spectra 20MM Breast Shield - Single (breast shield only)
Spectra 20MM Breast Shield Set - includes breast shield, valve, tubing and backflow protector
Spectra 20MM Double Pump Kit - 2 breast shields, 2 valves, 2 tubing, 2 backflow protector, 2 bottles

Spectra Large Breast Shield -28mm
The 28mm breast flange is a good choice if you are pumping with the standard 24mm flange and there is no room for freedom of movement in flange shaft.  You may experience too little compression of the milk sinuses if your flange is too small as the nipple is filling the shaft and the areola is not being engaged for compression.  The Spectra 28MM breast shield can be purchased in the following ways:

Spectra 28MM Breast Shield - Single (breast shield only)
Spectra 28MM Breast Shield Set - includes breast shield, valve, tubing and backflow protector
Spectra 28MM Premium Accessory Kit - breast shield, valve, tubing, backflow protector, bottle set
Spectra 28MM Double Pump Kit - 2 breast shields, 2 valves, 2 tubing, 2 backflow protector, 2 bottles

Spectra X-Large Breast Shield -32mm
The 32mm breast flange is a good choice if you have wider nipples.  You may experience too little compression of the milk sinuses if your standard or large flange is too small as the nipple is filling the shaft and the areola is not being engaged for compression.  Most women who use this size note that their nipples are wide such as the width of your thumb.  The Spectra 32MM breast shield can be purchased in the following ways.

Spectra 32MM Breast Shield - Single (breast shield only)
Spectra 32MM Breast Shield Set - includes breast shield, valve, tubing and backflow protector
Spectra 32MM Double Pump Kit - 2 breast shields, 2 valves, 2 tubing, 2 backflow protector, 2 bottles

Remember, breast shield flange sizing is important for milk extraction and in turn milk production so one way to be sure to get the right size is to purchase more than one size in the single flange and then once you determine your needs, purchase more in the appropriate size.  

Best wishes for the perfect flange size!
