FAQs

Is this cap dishwasher safe?

Yes, the Nalgene Wide Mouth Loop Top Replacement Cap is top-rack dishwasher safe for easy cleaning.

Will this fit my 500ml Nalgene bottle?

No, this cap is specifically designed for 1000ml wide-mouth bottles. It will not fit narrow-mouth or smaller capacity bottles.

Does it include the rubber gasket?

The cap is designed to create a seal based on its precision threading; ensure your bottle's rim is smooth and undamaged for the best seal.

Can I use this on non-Nalgene bottles?

It is designed for most branded 1000ml wide-mouth bottles, but we recommend verifying that your bottle has a standard wide-mouth thread pitch.

Is the material BPA-free?

Yes, all Nalgene components are manufactured using BPA-free materials to ensure safe hydration.

Troubleshooting

The cap is leaking when tightened.

Ensure the cap is not cross-threaded. Unscrew it completely and re-attach, ensuring it sits level before tightening.

Cap feels stiff or difficult to turn.

Clean the threads on both the bottle and the cap to remove any grit or dried beverage residue that may be creating friction.

Setup, Compatibility & Care

To install the cap, ensure the threads on your existing bottle are clean and free of debris. Simply align the cap with the bottle opening and rotate clockwise until you feel it seat firmly. Do not overtighten, as this can wear out the threads over time. To maintain the integrity of the seal, wash the cap regularly with warm, soapy water and a bottle brush to prevent bacteria buildup. Always allow the cap to air dry completely before securing it back onto the bottle to ensure the internal gasket remains clean and effective.
