Clear PVC Tubing – Food Grade Flexible Plastic Hose for Air, Water, Aquarium & Pond

Match the ID (inner diameter) to the outer diameter of your barb fitting or nozzle. For example, a 6mm barb typically requires a hose with a 6mm ID. The OD (outer diameter) matters when the hose must pass through a clamp, bulkhead, or conduit. To convert mm to inches, divide by 25.4 — for example, 6mm ID ≈ 1/4", 12mm ID ≈ 1/2", 25mm ID ≈ 1". Wall thickness = (OD − ID) ÷ 2, so a 6mm × 8mm hose has a 1mm wall on each side.

This clear PVC flexible hose is generally suited for low-to-moderate pressure applications such as gravity-fed water systems, aquarium return lines, and air supply lines. It is not typically recommended for high-pressure hydraulic or industrial plumbing. For pressurized domestic water lines, contact us to confirm the pressure rating for your specific size before ordering.

Clear PVC tubing is generally designed for indoor or sheltered outdoor use. Prolonged UV exposure can cause the material to yellow and become brittle over time. For outdoor pond or garden irrigation runs, routing the hose through UV-resistant conduit or keeping it shaded is typically recommended to extend service life.

Yes — this tubing is listed as food-grade PVC, meaning it is generally manufactured without harmful plasticizers or additives. It is commonly used for home brewing wort transfer, aquaponics water lines, and drinking water filtration systems. For regulated commercial food-processing environments, please verify compliance with your applicable local standards (e.g., NSF/ANSI 61) before use.

This hose is compatible with standard barb fittings where the barb OD matches the hose ID (e.g., a 6mm ID hose fits a 6mm barb). Push-fit and compression fittings sized to the hose OD are also generally compatible. For secure connections on pressurized lines, use a hose clamp over the barb. No adhesive or solvent cement is needed for barb connections.

A sharp utility knife or dedicated tubing cutter gives the cleanest, squarest cut — important for a leak-free seal at fittings. Score around the circumference first, then cut through in one controlled pass. For larger diameters (25mm ID and above), a fine-tooth hacksaw or ratchet-style PVC pipe cutter is generally easier to control. Deburr the cut edge lightly before pushing onto a barb fitting.

Smaller diameters (2mm–8mm ID) are quite flexible and resist kinking at moderate bend angles. Larger diameters require a wider bend radius to maintain full bore flow. If a tight bend is unavoidable, briefly warming the hose section in warm water (not boiling) increases flexibility without damaging the PVC. Alternatively, use an elbow fitting at sharp corners for larger sizes.
