CO2 Art Resistant Tubing is premium, high-pressure-rated polyurethane tubing designed specifically for planted aquarium CO2 systems. Unlike many cheaper tubes on the market, it's made from a material that won't turn brittle or start leaking gas over time, so it holds up reliably for the long haul rather than needing regular replacement.
This clear 6m (20ft) length gives you plenty to run a full CO2 line from regulator to diffuser, with enough spare for repositioning equipment or longer runs on larger tanks. It's compatible with all CO2 Art glass diffusers and accessories.
Tip: to attach the tubing to CO2 glassware, dip the end in boiling water for a couple of seconds first — this softens it slightly, making it easy to push onto fittings for a secure, leak-free seal.
