The Spectra Breast Shield Set is a complete replacement kit for your Spectra breast pump, bringing together the milk-path and vacuum parts that naturally wear over time. Each set includes a breast shield (flange), a duckbill silicone valve, a backflow protector and spare tubing — everything you need to refresh a single side of your pumping setup and get back to expressing with parts that fit and seal properly. It's compatible with the Spectra S1, S2 and Q breast pumps.
Soft pump parts don't last forever. Valves lose their spring, seals stop sitting snugly, and you may notice suction feeling weaker than it used to. Keeping a fresh set on hand means you're never caught out when a part starts showing its age — and because Spectra recommends replacing your parts every 3 to 6 months for optimal use, having a spare kit ready makes that routine swap simple.
Choosing your breast shield size
The set is available in 16 mm, 20 mm, 24 mm, 28 mm and 32 mm, so you can match the flange to your own fit rather than settling for a one-size approach. Flange size isn't reliably guessed from bra size, so it's worth choosing the diameter that suits you — a comfortable, well-aligned fit makes a real difference to how expressing feels day to day.
How it Works
- Breast shield (flange): The funnel-shaped part that sits against the breast and channels milk down through the set as the pump draws its vacuum.
- Duckbill silicone valve: A flexible one-way valve that opens and closes as the pump cycles; a valve that seals well helps the pump hold its suction.
- Backflow protector: Sits between the milk-collection parts and the tubing to help keep milk from travelling back towards the tubing and motor, which maintains a closed system for hygiene and motor protection.
- Tubing: The air path that connects the set to the pump motor.
Best For
The Spectra Breast Shield Set is a great option for parents who:
- Own a Spectra S1, S2 or Q pump and want a straightforward all-in-one replacement for worn parts
- Like to keep a spare set on hand so a torn valve or tired seal never interrupts a session
- Want to fine-tune their fit by choosing a specific flange size
Pandylane Pro Tip
This set is sold individually and covers one side. If you double pump, you'll need two sets so both sides are working with fresh parts at the same time.
