Straight Joiner Tubing Plastic Barbed Connector Pipe Hose Air Water 1.6mm - 25mm

Match the connector's outer diameter (OD) to your tubing's inner diameter (ID). For example, if your hose has a 6 mm inner bore, select the 6 mm OD connector. For flexible silicone or PVC tubing, a connector OD equal to or slightly larger than the tubing ID creates a tighter barbed seal. Measure your tubing ID with calipers before ordering.

Yes. The rigid plastic material is suitable for air and fresh-water applications at typical DIY working pressures. They are commonly used in pneumatic hobby lines, garden irrigation, aquarium plumbing, and automotive washer-fluid tubing. For high-pressure or chemical-media applications, contact us to confirm compatibility before use.

For standard flexible hose (silicone, PVC, polyurethane) at low-to-moderate pressures, the barbed profile provides a secure push-fit hold without clamps or adhesive. For higher-pressure lines or rigid tubing, hose clamps are recommended as an additional safeguard. Always test the joint before putting the line into service.

The 7.9 mm OD corresponds to the imperial 5/16-inch nominal size commonly used in North American automotive and pneumatic tubing, while the 8 mm OD is the metric equivalent used in European and metric-standard hose. Measure your tubing's inner diameter carefully — a 0.1 mm difference can affect seal tightness on rigid tubing, though flexible hose typically accommodates both.

Yes, in most cases. The rigid plastic barbs are not designed to be single-use, and the connector can typically be removed and reinserted into the same or a new hose section. However, repeated removal from the same hose end may gradually enlarge the bore and reduce seal integrity. Inspect the tubing end for deformation before reuse.

Rigid plastic (nylon/polypropylene) does not rust or corrode, making these connectors well-suited for outdoor irrigation systems, garden hose repairs, and damp workshop environments. Prolonged UV exposure may cause gradual embrittlement in some plastics; for permanent outdoor installations, consider protecting the joint from direct sunlight or use UV-stabilized tubing over the connector.

A single-line repair typically requires 1 connector. For a drip-irrigation grid with multiple branch joins or a workshop air-line network, ordering a 10- or 20-piece pack reduces per-unit cost and ensures you have spares on hand. The 50- and 100-piece packs offer the best per-piece value for system builds or workshop stock.
