How to Replace a Sport Cap Maintenance Kit

Quick answer

Replace the removable spout and air vent gasket on your Klean Kanteen Sport Cap with the Sport Cap Maintenance Kit. No tools needed.

How to replace the Sport Cap gaskets

1. Remove the old spout: Pull the existing removable spout straight out from the cap. It should come off with a firm tug. If it's stuck, twist gently while pulling. Don't use tools; they can damage the cap body.
2. Remove the old air vent gasket: Flip the cap over and push out the small air vent gasket (plug) from the underside. Use your thumb or a soft tool to avoid scratching the plastic. Make sure the vent hole is clear of debris before inserting the new gasket.
3. Install the new air vent gasket: Press the new air vent gasket into the vent hole from the underside of the cap. It should sit flush and snug. Check that it doesn't protrude above the surface. Insert it straight; twisting can cause a poor seal.
4. Install the new removable spout: Align the new spout with the opening on top of the cap and push it in until it clicks into place. Give it a gentle tug to confirm it's secure. If the spout feels loose, remove and reinsert it; it should not slide out easily.
5. Test the cap: Fill your bottle with water, close the cap, and tip it upside down over a sink. Check for leaks around the spout and vent. Then open the spout and drink to confirm smooth flow. If it leaks, recheck that both gaskets are fully seated.
