Not all memobottle lids are the same. Learn which lid fits your bottle, when to replace it, and how to get a leak-proof seal every time.
Quick answer
The memobottle lid you need depends entirely on which bottle range you own. Original memobottles use a different lid than the Stainless Steel range, and they are not interchangeable. If you have a Stainless Steel memobottle, the Copper Lid is your only compatible replacement. If you have an Original memobottle, look for the standard lid designed for that series.
Original vs Stainless Steel: Two Different Lid Systems
memobottle produces two distinct bottle families: the Original (BPA-free plastic) range and the Stainless Steel range. Each uses a lid designed specifically for that material and threading. You cannot swap a lid from an Original bottle onto a Stainless Steel bottle, or vice versa. Attempting to force a mismatched lid can damage the threads and break the seal.
If you own an Original memobottle, your replacement lid must be the standard Original lid. If you own a Stainless Steel memobottle, your only compatible spare or replacement is the Copper Lid (Stainless Steel memobottle). The Copper Lid is built with a stainless steel construction and a durable silicone seal to match the metal body.
When to Replace Your memobottle Lid
A worn or damaged lid is the most common cause of leaks. Replace your lid if you notice cracks, stripped threads, or a silicone seal that has become hard or deformed. Even without visible damage, the silicone seal can lose flexibility over time, especially if exposed to high heat or frequent dishwasher cycles. Replacing just the lid is often cheaper than buying a whole new bottle.
The Copper Lid for Stainless Steel memobottles is available as a standalone purchase, so you can keep your existing bottle in service. For Original memobottles, check the memobottle accessories section for the standard lid. Always verify compatibility with your bottle's range before ordering.
Fit and Seal: What to Check
A properly fitted lid should screw on smoothly without resistance and tighten with a slight final turn. The silicone seal should sit evenly inside the cap without bulging or gaps. After closing, turn the bottle upside down and shake gently to confirm no water escapes. If you see moisture, the lid may not be seated correctly, the seal may be dirty, or the lid may be incompatible.
The Copper Lid for Stainless Steel memobottles uses a silicone seal that is designed to be leak-proof when properly tightened. Clean the seal and bottle threads regularly with warm soapy water to prevent debris from breaking the seal. Avoid overtightening, which can compress the silicone and reduce its effectiveness over time.
Decision rules for choosing your memobottle lid
- Check your bottle range first: Look at the bottom or original packaging to confirm whether you have an Original (plastic) or Stainless Steel memobottle. The lid systems are not cross-compatible. Buy the lid that matches your bottle range.
- Inspect the seal condition: If your current lid leaks, examine the silicone seal for cracks, hardening, or debris. A damaged seal cannot be repaired; replace the entire lid. Replace the lid, not just the seal.
- Buy the right spare for Stainless Steel: The Copper Lid is the only spare or replacement lid available for the Stainless Steel memobottle range. It is sold separately and works with all sizes in that series. For Stainless Steel, choose the Copper Lid.
- Confirm fit before use: After installing a new lid, always perform a quick upside-down shake test with water. If it leaks, recheck alignment and cleanliness before assuming the lid is defective. Test the seal before carrying your bottle.
