Quick answer
The Spectra Premium Accessory Kit gives you all the replacement parts needed for single pumping: a flange, duckbill valve, backflow protector, tubing with adapter, and a molded-grip bottle with nipple and cap. Choose the flange size that matches your current fit.
Why replace pump parts regularly
Breast pump parts wear out over time. Duckbill valves can lose their seal, backflow protectors may crack, and tubing can develop tiny holes. Replacing these parts restores suction and helps maintain consistent milk expression. The Premium Accessory Kit bundles the most common wear items so you don't have to order each piece separately.
The kit comes in 20mm, 24mm, or 28mm flange sizes. If you already know your flange size from a previous fitting, order the same size. If you're unsure, measure your nipple diameter and add 2–4mm for a comfortable fit.
Trade-offs to consider
This kit is designed for single pumping only. If you double pump, you'll need two kits or separate replacement parts for each side. The kit includes one bottle set, which is convenient for immediate use, but you may want additional bottles for storing milk throughout the day.
The included tubing works with Spectra pumps. If you use a different brand of pump, check compatibility before purchasing. The flange, valve, and backflow protector are Spectra-specific and may not fit other pump systems.
Decision rules for ordering your kit
- Choose your flange size: Measure your nipple diameter before pumping. Add 2–4mm to that measurement to find your ideal flange size. The kit is available in 20mm, 24mm, or 28mm. If you're between sizes, try the larger one for comfort.
- Know what's included: The kit contains exactly one of each: flange, duckbill valve, backflow protector, tubing with adapter, and a 5oz bottle with nipple, disc, cap, and cover. If you need two of any item (e.g., for double pumping), order a second kit or buy the individual parts. For double pumping, you need two kits or separate replacement parts for the second pump side.
- When to replace each part: Replace duckbill valves every 2–3 months or when you notice reduced suction. Replace backflow protectors every 3–6 months or if they show cracks. Tubing can last 6–12 months but replace it sooner if it develops kinks or holes. Flanges typically last 6–12 months unless damaged. Mark your calendar to check these parts quarterly for optimal pump performance.
