What the accessory set contains
- What is in a breast pump accessory set?
- The Lansinoh Breast Pump Accessory Set is a bundled replacement-parts kit. The single set includes 2 white valves, 1 diaphragm, 1 diaphragm cap, 1 breast cushion body, 1 160ml container, 1 tubing set suitable for single or double pumps, 1 25mm breast cushion, 1 30.5 breast cushion and 1 container lid.
- How is the double set different?
- The double set doubles the parts count: 4 white valves, 2 diaphragms, 2 diaphragm caps, 2 breast cushion bodies, 2 160ml containers, 1 tubing set suitable for single or double pumps, 2 25mm breast cushions, 2 30.5 breast cushions and 2 container lids. The tubing set is listed once in both versions.
- Does the set include a pump motor?
- No. The supplied contents list covers valves, diaphragms, caps, cushion bodies, breast cushions, containers, lids and tubing. The motor or pump unit itself is not part of the listed contents, so this is a parts kit rather than a complete pump.
Single or double: match the kit to how you pump
The single set gives you one set of the soft parts and one container, while the double set gives you two of each. If you usually pump one side at a time, the single kit covers the parts in the list. If you pump both sides together, the double set means you are not short of a valve, diaphragm, cushion or container when both sides are in use.
The tubing set is described as suitable for single or double pumps in both versions, so the tubing entry is not the deciding factor between the two sizes. The difference is the number of valves, diaphragms, caps, cushion bodies, containers, breast cushions and lids.
When a spare parts kit is useful
- When does a spare pump parts kit help most?
- A spare kit is most useful when you want replacement parts on hand in one go rather than sourcing individual pieces. The set is described as a way to stock up on replacement parts together, which suits households that would rather keep a full spare set in the cupboard than hunt for one small part at a time.
- Is this a pump accessory set for travel?
- It can work as a travel kit if you want spare valves, diaphragms, cushions, a container and tubing packed together. Whether it fits your travel routine depends on your pump and your bag, and the supplied information does not list a carry case or travel-specific storage, so treat it as a parts bundle rather than a dedicated travel system.
- Does the set tell me when to replace parts?
- The supplied information describes the contents and the stocking-up purpose but does not give a replacement schedule. If you need timing guidance, check your pump's own instructions rather than assuming a fixed interval from this set.

Practical questions before you open the box
- Which breast cushion size is included?
- Both sets list a 25mm breast cushion and a 30.5 breast cushion. The supplied information does not say which breast size each cushion is intended for, so use the listed measurements as your reference and check your pump's fitting guidance if you are unsure.
- Can I return the set if I change my mind?
- The product note says that, for health protection and hygiene reasons, once opened the product may not be returned, and that your statutory rights are not affected. If you are unsure about the single versus double choice, decide before opening.
- Does the set include cleaning instructions?
- The supplied information does not list preparation or cleaning steps for these parts. Follow the cleaning guidance that came with your pump and the parts you are replacing rather than assuming a method from this listing.
