Clear PVC Hose Tube — Food Grade Flexible Plastic Pipe for Aquarium, Water & Air Lines (ID 2–13mm)

Match the tube's inner diameter (ID) to the outer diameter of your barbed fitting or nozzle. For example, a 6mm barb typically requires a 6mm ID tube. If you're between sizes, sizing up by 1mm generally gives a snug push-fit. Available sizes range from 2mm to 13mm ID — select the variant that matches your fitting's barb OD.

Quick reference: 1/8" ≈ 3mm | 3/16" ≈ 5mm | 1/4" ≈ 6mm | 5/16" ≈ 8mm | 3/8" ≈ 10mm | 1/2" ≈ 13mm.

ID (inner diameter) is the clear opening through which fluid flows — this is the measurement you match to your fitting. OD (outer diameter) is the total width including the tube wall. For example, the 6×8mm variant has a 6mm ID and an 8mm OD, meaning the wall is typically 1mm thick on each side.

Yes. This tubing is made from food-grade PVC compound, making it generally suitable for potable water lines, aquarium water circulation, and beverage dispensing. It does not contain plasticizers that leach into water under normal operating conditions. For aquarium use, rinsing the tube before installation is always a good practice.

Clear PVC tubing is not UV-stabilized and will typically yellow and become brittle with prolonged direct sunlight exposure. For permanent outdoor runs, routing the tube through conduit or shading it is recommended. For short-term or shaded outdoor use — such as garden irrigation or temporary water transfer — it generally performs well.

Working pressure and temperature vary by wall thickness and diameter. Smaller diameters with thicker walls typically handle higher pressures. In most cases, clear PVC tubing is rated for low-to-medium pressure applications — generally up to 40–60 PSI for smaller sizes — and a temperature range of approximately 32°F–140°F (0°C–60°C). For pressure-critical applications, contact us to confirm the rating for your specific size.

This flexible PVC tubing is designed to resist kinking under normal bending conditions. Smaller diameters (2–5mm ID) are more flexible and can bend tightly without kinking. Larger diameters (8–13mm ID) have a larger minimum bend radius — typically 3–5× the OD — to avoid flow restriction. Avoid sharp 90° bends on larger sizes; use an elbow fitting instead.

This tubing is compatible with standard barbed fittings, push-fit connectors, and hose clamps sized to match the ID. For aquarium use, it fits most common air pump outlets and powerhead barbs. For plumbing or automotive use, match the ID to the barb OD for a secure, leak-resistant connection. Hose clamps are recommended for any pressurized application.

A sharp utility knife or dedicated tube cutter gives the cleanest square cut. Scissors can be used for smaller diameters (2–5mm ID) but may slightly compress the tube end. Always cut perpendicular to the tube axis — a square, flat end ensures a leak-free seal against barbed fittings and push-fit connectors.
