Spectra Loose Breast Shield

The Spectra Loose Breast Shield is a spare flange for Spectra electric breast pumps, giving you a way to swap in a different size or replace a shield that's showing wear. It's the part your breast rests against while pumping, and getting the size right makes a real difference to how comfortable expressing feels. This one fits all electric Spectra breast pumps and is compatible with the Spectra S1, Spectra S2 and Spectra Q, so you can match it to the pump you already own.

Spectra pumps are issued with a standard 24 mm shield, but every body is different and the standard size won't suit everyone. This loose breast shield is available in 16 mm, 20 mm, 24 mm, 28 mm and 32 mm, so you can buy the exact size you need rather than a full new kit. The shields are clear, BPA-free, easy to clean and easy to install, and they fit directly onto the wide-necked bottles used with Spectra breast pumps.

Finding the right size

Flange sizing isn't reliably guessed from bra size or the size your pump happened to arrive with — it comes down to your own fit and comfort while expressing. Having the option to step up or down a size lets you dial in a shield that sits comfortably, which is why buying a loose flange on its own is often all you need.

Best For

The Spectra Loose Breast Shield is a great option for parents who:

• Own a Spectra S1, S2 or Q and need a size other than the standard 24 mm
• Want to replace a worn or damaged shield without buying a full new set
• Prefer to keep a spare on hand to shorten cleaning turnaround

Pandylane Pro Tip

This breast shield is sold individually, so if you double pump you'll want to order two — one for each side. It can also be worth keeping a spare in a second size while you work out which fit feels most comfortable for you.
