Learn how to get the right fit, use your Thrive 2-in-1 flange effectively, and care for it to keep your PowerPump set working well.
Quick answer
The Thrive 2-in-1 flange is designed for the PowerPump set. Getting the right size, using it correctly, and cleaning it properly will keep your pumping comfortable and efficient.
Why flange fit matters
A flange that is too small can pinch and cause pain; one that is too large may not create a good seal, reducing suction. The Thrive 2-in-1 flange comes in multiple sizes, so you can choose the one that matches your nipple diameter after pumping.
If you are unsure about your size, measure your nipple before pumping (not after) and add 2-4 mm for a comfortable fit. The flange should pull in your nipple without rubbing the sides.
Daily care extends flange life
Like all pump parts, the Thrive 2-in-1 flange wears over time. Washing after each use with warm soapy water and air drying helps maintain the silicone's seal. Avoid boiling or dishwasher cycles unless the manufacturer says it's safe, as high heat can degrade the material.
Replace the flange if you notice cracks, tears, or a change in suction. Having a spare set on hand (like the Thrive 2-in-1 Breast Pump Flange for PowerPump Set) means you can keep pumping while the other set dries.
How to fit, use, and care for your Thrive 2-in-1 flange
- 1. Choose the right size: Measure your nipple diameter (not the areola) before pumping. Add 2-4 mm to find your flange size. The Thrive 2-in-1 flange is available in several sizes; pick the one that allows your nipple to move freely without rubbing the tunnel walls. Common mistake: using a size that feels tight or leaves a gap. A proper fit should be snug but not painful.
- 2. Attach and position the flange: Center your nipple in the flange opening and press the flange firmly against your breast to create a seal. Hold it in place or use a pumping bra to keep hands free. The 2-in-1 design works with the PowerPump set, so ensure the connector is fully seated. Checkpoint: if you hear air hissing, the seal is broken. Adjust the angle or press the flange more firmly.
- 3. Clean after every use: Rinse the flange with cool water immediately after pumping to remove milk residue. Wash with warm soapy water and a dedicated brush. Rinse well and air dry on a clean towel. Avoid using abrasive sponges that can scratch the silicone. Common mistake: leaving milk to dry on the flange can cause odors and reduce suction over time.
- 4. Inspect and replace as needed: Check the flange for wear every few weeks. Look for cracks, sticky spots, or loss of shape. If the flange no longer seals well or feels different, replace it. The Thrive 2-in-1 Breast Pump Flange for PowerPump Set is sold separately for easy replacement. Checkpoint: if your pumping output drops or you notice more discomfort, the flange may need replacing.
