Clear PVC Flexible Tubing 2–8mm ID — Hose Pipe for Water, Air, Fuel, Oil & Aquariums

Match the inner diameter (ID) to your fitting or nozzle OD. For example, a 4 mm OD barb fitting typically requires a 4 mm ID tube (the 4×6 mm variant). For length, measure your full run and add 10–15% for routing slack. Available lengths range from 1 m (≈3.3 ft) to 50 m (≈164 ft), so you can order exactly what you need without splicing.

Clear PVC flexible tubing generally handles low-to-medium pressure applications. Working pressure varies by wall thickness and diameter — typically in the range of 30–90 PSI for smaller diameters at room temperature. Pressure rating decreases as temperature increases. For pressurized systems, please contact us to confirm suitability before ordering.

Standard clear PVC tubing is not UV-stabilized and may yellow or become brittle with prolonged direct sunlight exposure. For outdoor installations, we recommend routing the tube through conduit, shielding it with a UV-resistant sleeve, or replacing it periodically. It performs well in shaded or indoor outdoor environments.

This clear PVC hose is widely used for aquarium airline tubing, pump connections, and filter lines. PVC is generally considered aquarium-safe for freshwater and saltwater applications when used within its temperature range. Rinse the tube with clean water before first use. If you keep sensitive species, consult your aquarium supplier for confirmation.

This clear PVC hose is generally suitable for light fuel and oil transfer in low-pressure, non-critical applications — such as small engine gravity-feed fuel lines or light mineral oil systems. It is not recommended for aromatic fuels (e.g., high-ethanol blends, gasoline under pressure) or aggressive solvents. Always verify chemical compatibility before use in fuel systems.

This tubing is designed to slip over standard barb fittings. Select a barb whose OD matches the tube's inner diameter for a secure, leak-resistant connection. Hose clamps are recommended for any pressurized water or air line. The tubing is compatible with plastic, brass, and stainless steel barb fittings commonly available at hardware stores.

Clear PVC flexible tubing typically performs well between 32°F (0°C) and 140°F (60°C). At higher temperatures, the tube may soften and lose its pressure rating. For hot-water lines, steam, or high-heat environments, a silicone or PTFE alternative is recommended. Cold temperatures down to freezing are generally fine, though the tube may stiffen slightly.
