How to Replace Wide Cap Gaskets on Your Bottle

Quick answer

To replace wide cap gaskets, remove the old gasket from your cap, install the new one from the Klean Kanteen Wide Cap Gasket kit, and ensure it's seated evenly before reusing the bottle.

Steps to replace wide cap gaskets

1. Remove the old gasket: Unscrew the cap from your bottle. Use your fingernail or a blunt tool to gently pry the old gasket out of the groove inside the cap. Be careful not to scratch the plastic or metal. A common mistake is using a sharp tool that can damage the cap. Stick to your fingers or a plastic spudger.
2. Clean the groove: Wipe the groove where the gasket sits with a damp cloth to remove any dirt or residue. Let it dry completely before installing the new gasket. Residual moisture or debris can prevent the new gasket from sealing properly.
3. Install the new gasket: Take one gasket from the kit and press it evenly into the groove. Run your finger around the entire circumference to ensure it's seated flat and not twisted. If the gasket is twisted or not fully seated, the cap may still leak. Double-check the fit before reassembling.
4. Test the seal: Screw the cap back onto the bottle, fill it with water, and turn it upside down over a sink. Check for any leaks around the cap threads. If you see leaks, remove the cap and reseat the gasket. A small adjustment often fixes the issue.
