Red Sea RCP Cap Tube (2pcs)
The small dosing-bottle spare worth keeping on hand. This two-pack of cap tubes fits the bottle caps used across Red Sea's Reef Care Program dosing range — the short internal tube that lets your ReefDose or manual doser draw liquid cleanly from the bottle without air gaps or drips.
Key features
- Genuine Red Sea spare — matches the cap fitted to Reef Care Program dosing bottles.
- Two tubes per pack — enough to service two bottles, or keep one spare.
- Keeps dosing clean — a cracked or perished cap tube is a common cause of a drippy, messy dosing bottle.
- Quick swap — pulls out and pushes in by hand, no tools needed.

Common questions
What does the cap tube actually do?
It's the short tube inside the bottle cap that the dosing tubing connects to — it keeps the draw sealed and drip-free.
How often does it need replacing?
Only when it perishes, cracks, or starts weeping around the cap — there's no fixed schedule from Red Sea for this part.
Does this include the bottle or cap itself?
No — this is the tube only. The bottle and cap are separate.
