Replacement bottle cap for magnetic-mechanical bottle mounting system

All bottles and their matching caps age - even the TWIST bottles are not magic. If the old bottle is still fine, but the cap is worn down, chewed up, or developed leaking, simply replace it with the bottle cap suitable for TWIST bottle 590 and TWIST bottle 450.

Features:

• Replacement bottle cap with high flow, self-sealing and leak-proof valve, and optional dirt cover.
• Only suitable for TWIST bottle 590 and TWIST botte 450
• Not suitable with other TWIST bottles
