This valve bottle cap is compatible with Fidlock TWIST bottles in 800ml, 590ml, and 450ml sizes. It is not compatible with other TWIST bottle models, especially those marked 'Made in Taiwan'.
Check the size of your TWIST bottle (800, 590, or 450ml). If your bottle has 'Made in Germany' or 'Made in EU' printed on it, it is likely compatible. If it has 'Made in Taiwan', this cap will not fit.
The valve cap should be replaced when it shows signs of wear, such as leaking, difficulty in opening/closing, or damage to the valve or sealing surfaces. This depends on usage frequency and care.
No, it is recommended to hand wash the valve cap with warm water and mild soap. Dishwashers may damage the sealing components and the valve.
This item is a replacement valve cap sold separately. It is intended to replace an existing cap on a Fidlock TWIST bottle.
The optional dirt cover snaps onto the valve to protect it from dust, dirt, and other contaminants when not in use, ensuring a cleaner drinking experience.
Ensure the valve cap is securely screwed onto the bottle. Check for any debris on the threads or sealing surfaces. If the valve itself appears damaged, it may need replacement.
Check if the valve is fully open when you bite down. Ensure there is no blockage in the valve or dirt cover. Clean the valve area with warm water.
Verify that you are using a compatible TWIST bottle model. Ensure the bottle threads are clean and free of any damage. Align the cap carefully before attempting to screw it on.
