The Gem Silicone Parts Pack is a complete set of replacement silicone consumables for the Gem Pump, bringing together the parts that naturally wear over time into one convenient pack. It includes the silicone diaphragm, duckbill valves, O-ring seals and a flange in your chosen size, so you can refresh the soft, milk-contact and vacuum-seal components of your pump in a single purchase.
These are the parts that do the quiet work in any breast pump: the pieces that flex, seal and open with every cycle. Because they're made from food grade silicone and used repeatedly, they're considered consumable parts and are meant to be replaced from time to time to help keep your Gem Pump working efficiently. Buying them as a pack means you're not tracking down individual spares one at a time.
What's in the pack
The pack gives you a full silicone refresh for your Gem Pump: the diaphragm, a pair of duckbill valves, the O-ring seals and a single flange in the size you select. You can choose your flange from three breast shield sizes — 18mm, 20mm or 22mm — so you can match the fit you already know works for you.
How it works
- Diaphragm: This flexible silicone piece moves with the pump's action and is central to how the pump draws and holds its vacuum.
- Duckbill valves: These soft one-way valves open and close through each cycle; when they stay supple and seal well, they help the pump maintain suction.
- O-ring seals: These keep the connections snug so the vacuum isn't lost at the joins.
- Flange: The breast shield your nipple sits in during expressing, supplied here in your selected 18mm, 20mm or 22mm size.
Best For
The Gem Silicone Parts Pack is a great option for parents who:
- Own a Gem Pump and want to replace worn or damaged silicone parts
- Would rather refresh all the soft consumables at once than order pieces individually
- Already know their flange size and want to match it (18mm, 20mm or 22mm)
It may not be the fit you're after if you use a different pump brand or model, as these parts are made for the Gem Pump.
Pandylane Pro Tip
It helps to keep a spare set of duckbill valves and a diaphragm on hand before your current ones show signs of wear — soft silicone parts can tear or lose their springiness with regular use, and having replacements ready means no pause in your pumping routine.
