True Metric Tubing for Metric Barbed Fittings and European-Built Equipment This metric 25 mm kink free pond tubing provides 100 ft (30.5 m) of flexible black tubing made for true metric barbed fittings, the standard on many European-built pond pumps, pressure filters, and UV clarifiers, including Oase equipment. A smooth interior wall minimizes friction loss so your pump delivers closer to its rated flow, while the spiral ribbed exterior resists crushing under rock and soil. Metric Sizing Matters for a Leak-Free Seal Nominal 1" tubing is cut for 25.4 mm North American barbs, so a true 25 mm hose tail sits slightly loose inside it and depends on the clamp alone to seal. This metric version matches the tail properly for a secure, leak-free joint. If your system uses standard North American fittings, our standard 1" kink free hose is the right choice instead. The tubing is rated from -26°C to 88°C (-15°F to 190°F) and handles Canadian shoulder-season installs without cracking.
