Clear PVC Tubing — Flexible Plastic Hose for Water, Fish Tank, Auto & Garden (3mm–10mm ID)

Match the inner diameter (ID) to the outer diameter of your fitting or barb. For example, a 4mm barb fitting typically requires 4×6mm tubing (4mm ID). Measure your fitting first — a snug fit prevents leaks. If you're between sizes, size down for a tighter seal. As a reference: 3mm ID ≈ 1/8", 5mm ID ≈ 3/16", 8mm ID ≈ 5/16", 10mm ID ≈ 3/8".

Standard flexible PVC tubing generally handles low-to-medium pressure — typically up to 30–60 PSI depending on wall thickness and temperature. This tubing is well-suited for gravity-fed systems, aquarium pumps, and automotive overflow reservoirs. For high-pressure hydraulic or pneumatic applications, please contact us to confirm suitability before ordering.

Clear PVC tubing is generally moisture-resistant and performs well in wet environments including garden irrigation and outdoor fluid routing. However, prolonged direct UV exposure can cause gradual yellowing and reduced flexibility over time. For permanent outdoor installations, shielding the tubing from direct sunlight — or using UV-resistant sleeving — will extend its service life.

Yes. This clear PVC flexible hose is widely used in aquarium air pump lines, canister filter return hoses, and sump plumbing. PVC is generally considered non-toxic under normal aquarium conditions. Flush the tubing thoroughly with clean water before introducing it to a fish tank to remove any manufacturing residue.

This tubing is compatible with standard barb fittings, push-to-connect fittings, and worm-drive hose clamps sized to match the inner and outer diameter of your chosen variant. The PVC material stretches slightly over barb fittings for a snug, leak-resistant seal. Always verify the barb OD matches the tubing ID — for example, use 6×8mm tubing with a 6mm barb fitting.

Yes. PVC tubing cuts cleanly with a sharp utility knife, scissors, or a dedicated tubing cutter. We offer lengths from 1M (≈39.4") up to 10M (≈393.7"). Select the length closest to your project needs — each order ships as a single continuous piece. Cutting is straightforward and leaves a clean, square end suitable for fitting connections.

Flexible PVC tubing generally performs well between 32°F and 140°F (0°C–60°C). It may stiffen slightly in very cold conditions and can soften under sustained high heat. Avoid use with steam lines or near high-heat engine components such as exhaust manifolds. For coolant overflow reservoir lines, it is typically suitable as those lines carry low-pressure, moderate-temperature fluid.

The tubing is generally shipped coiled for compact packaging. PVC tubing in these smaller diameters (3mm–10mm ID) is flexible enough that any coil memory typically relaxes within a short time at room temperature. If needed, briefly warming the tubing with warm water will help it straighten quickly.
