Frequently Asked Questions
Q: What size is the AQUAPRO CO2 pressure air hose tube and what systems does it fit?
A: The AQUAPRO CO2 Pressure Air Hose uses a standard 4mm inner diameter × 6mm outer diameter sizing, which is compatible with the vast majority of aquarium CO2 regulators, diffusers, bubble counters, and water purifier connectors. Both the standard thickened air tube and TPU high-pressure variants share this sizing, so you can swap between them without changing your fittings.
Q: What is the difference between the standard thickened tube and the TPU high-pressure tube?
A: The standard thickened air tube is made from the same core material available across color options — it offers solid pressure resistance for everyday CO2 use in planted tanks. The TPU high-pressure tube is a step up, rated to approximately 10 kg of pressure, making it the better choice for high-output CO2 systems or water purifier applications where sustained pressure is required.
Q: How do I install the CO2 hose without damaging the tube or fittings?
A: It's simple — before connecting, briefly submerge the end of the tube in warm (not boiling) water for 20–30 seconds. This softens the material just enough to slip easily onto barbed fittings or regulator outlets without cracking the tube or requiring excessive force. Once cooled, the connection will firm up for a snug, secure fit.
Q: Can I use this tube for oxygen pump hoses or other aquarium accessories?
A: Yes! While designed primarily for CO2 delivery, the standard 4×6mm thickened air tube is also well-suited for general aquarium air pump lines, oxygen diffusers, and other accessories that use the same tubing diameter. The TPU variant is best reserved for high-pressure CO2 or purifier applications.
