Plastic Pagoda Tubes Reducer Joint 2 3 4Way Hose Connector Tube Splitter Fitting

Match the fitting's port diameter to your tube's inner diameter (ID), not the outer diameter. For example, if your silicone tube has a 6 mm inner diameter, select the 6 mm variant. A snug fit on the barb is normal — the stepped profile is designed to grip the tube wall. If the tube slides on too loosely, size down; if it won't seat at all, size up.

A reducer fitting has two different port diameters — for example, 12.7 mm on one end and 6.4 mm on the other. You need a reducer when connecting two tubes of different inner diameters in the same line, such as transitioning from a main supply tube to a smaller branch line. Without a reducer, you would need two separate fittings and an intermediate adapter.

Yes. The smaller diameter variants (1.6 mm – 4 mm) are commonly used with standard aquarium air tubing. The T Shaped, Y Shaped, and Cross-Shaped 4 Way options are particularly useful for splitting a single air pump output to multiple tanks or airstones. Ensure the port diameter matches your air tubing's inner diameter for a secure, leak-resistant connection.

Yes, these fittings are suitable for low-pressure liquid routing — including drip irrigation, aquarium water lines, and hobby coolant circuits — when used with compatible flexible tubing. They are not rated for mains water pressure or high-pressure pneumatic systems. For pressure-critical applications, contact us to confirm suitability before ordering.

The T Shaped fitting has three ports arranged at 90° angles — one inlet and two outlets branching left and right. The Y Shaped fitting has three ports at an angled Y configuration, which allows smoother flow splitting with less turbulence. The π-Shaped (4 Way) fitting has four ports in a parallel double-branch layout, useful for distributing one input to three outputs in a compact footprint. Choose based on your routing geometry and flow requirements.

For most low-pressure applications, the stepped pagoda barb profile provides sufficient grip without clamps or adhesive. The tube should slide onto the barb with moderate resistance and seat firmly against the shoulder. If you are working with higher flow rates, pulsating pressure, or tubing that has a looser inner diameter tolerance, adding a small zip tie or hose clamp near the barb base is recommended as a precaution.

Use the Amount option above to choose 1 Pcs or 5 Pcs. The 5 Pcs pack is priced lower per unit than buying five individual pieces, making it the better choice if you are building a branched network or want spares on hand. The 1 Pcs option is ideal for a single replacement or to test fit before committing to a larger quantity.
