90° Elbow Plastic Barbed Joiner Reducer Connector Pipe Tube Hose Water 1.6-25mm

Match the barb diameter to your tubing's inner diameter (ID), not the outer diameter. For example, if your tubing has a 6 mm inner bore, select the 6 mm barb size. A barb that is slightly larger than the ID will create a tighter grip; one that is too small will leak. When in doubt, measure your tubing ID with calipers before ordering.

A reducer connector has two different barb diameters — one on each end — allowing you to join two tubes of different sizes in a single fitting. For example, a 16–10 mm reducer connects a 16 mm tube on one side to a 10 mm tube on the other. Use a reducer when transitioning between tubing sizes without adding extra adapters in the line.

No. The barbed design creates a mechanical push-fit seal when flexible tubing is pressed firmly onto the barb. For low-pressure applications such as drip irrigation or aquarium plumbing, clamps are typically not needed. For higher-flow or vibration-prone setups, adding a hose clamp over the tubing at the barb is recommended for extra security.

Yes. The plastic construction is corrosion-resistant and holds up well in typical outdoor garden conditions. These fittings are commonly used in drip irrigation systems, raised-bed watering lines, and pond or water feature plumbing. Avoid prolonged direct UV exposure without tubing cover, as extended sunlight can degrade some plastics over time.

Yes, these connectors are widely used in aquarium filter plumbing and pond setups. The plastic material is water-safe for freshwater applications. Confirm the barb size matches your filter or pump tubing ID. For saltwater or chemically treated water, verify material compatibility before use.

Single-size options (e.g., "6mm" or "16mm") have the same barb diameter on both ends and are used to connect two tubes of identical size at a 90° angle. Reducer options (e.g., "6–4mm" or "16–10mm") have different diameters on each end, allowing a step-down connection between two different tube sizes in the same elbow fitting.

These fittings are suitable for low-pressure pneumatic tubing layouts in hobby and light-duty applications. They are not rated for high-pressure compressed air systems. For any pressurized application, confirm the operating pressure is within the fitting's tolerance and consider adding hose clamps for a more secure connection.
