Learn how to replace the gaskets on your Klean Kanteen TKWide Loop Cap with the TKWide Loop Cap Maintenance Kit. Step-by-step instructions included.
Quick answer
To replace the gaskets on your TKWide Loop Cap, use the TKWide Loop Cap Maintenance Kit. The process takes less than 5 minutes and requires no tools.
Why replace cap gaskets?
Over time, the ring gasket and low seal gasket on your TKWide Loop Cap can wear out, causing leaks or making the cap harder to twist. Replacing them restores the seal and extends the life of your bottle.
The TKWide Loop Cap Maintenance Kit is designed specifically for this cap model. It includes both gaskets you need in a single, low-cost package.
Step-by-step replacement guide
- Remove the old gaskets: Unscrew the TKWide Loop Cap from your bottle. Pull out the old ring gasket (the larger one) from the cap's inner groove. Then peel out the old low seal gasket (the smaller one) from the cap's underside. A common mistake is leaving old gasket residue behind; wipe the grooves clean with a dry cloth before installing the new ones.
- Install the new ring gasket: Take the new ring gasket from the kit and press it firmly into the inner groove of the cap. Run your finger around the groove to ensure it sits evenly and fully seated. If the gasket is not fully seated, the cap may leak when closed.
- Install the new low seal gasket: Place the new low seal gasket into the cap's underside recess. Press it in until it lies flat and flush with the surrounding plastic. Check that the gasket is not twisted or bunched up; a smooth, flat fit is essential for a leak-proof seal.
- Test the cap: Screw the cap back onto your bottle. Fill the bottle with water, close it tightly, and turn it upside down to check for leaks. If you see drips, remove the cap and reseat both gaskets. If leaks persist after reseating, the gaskets may be damaged or the cap may need replacement.
