Learn which Laken aluminum canteens work with the plastic replacement cap, how to identify your model, and how to fit it correctly.
Quick Answer
The Laken plastic cap fits the Classic aluminum canteens with numbers 111, 112, 121, 121FA, 121FR, 121FV, 301, 401, and 601. Check the number stamped on your bottle to confirm before ordering.
Why Compatibility Matters
Using the wrong cap can lead to leaks or a loose fit, which defeats the purpose of a reusable bottle. The plastic cap is designed to match the thread and opening of specific Laken aluminum models, so it's important to verify compatibility first.
The cap is lightweight and resistant, making it a practical choice for everyday carry. It provides a reliable seal without adding extra weight to your bottle.
How to Identify Your Model
Look for the model number printed on the bottom or side of your canteen. Common numbers include 111, 112, 121, 301, 401, and 601. If you don't see a number, check the original packaging or receipt.
If your model is not listed, the cap may not fit. In that case, consider measuring the thread diameter and comparing it with the cap's specifications, or contact Laken support for guidance.
