Overview
The Clear High‑Pressure CO₂ Tube is crafted from premium polyurethane (PU), designed to handle pressurized aquarium CO₂ systems safely and efficiently. Clear, durable, and kink‑resistant, it ensures reliable gas delivery from your regulator to diffuser without the permeability issues common with silicone or PVC tubing.
Key Features
- CO₂-resistant PU material: Resists degradation under pressure; rated for ~50 psi (≈3 bar), far exceeding typical aquarium demands (≤15 psi) .
- 4 mm inner / 6 mm outer: Compatible with standard CO₂ regulators, diffusers, bubble counters, and valves .
- Crystal clear and unobtrusive: Nearly transparent—ideal for maintaining a clean visual aesthetic in planted aquariums .
- Kink-resistant: Flexible yet firm, it maintains smooth bends without pinching, ensuring consistent CO₂ flow .
- Easy installation: Soften ends by immersing in hot water for a few seconds, then push onto fittings for a snug seal .
