Pipe coupling White Line WL-2170 for drip irrigation systems — 1 pc, made in Poland

White Line WL-2170 is a pipe coupling designed for drip irrigation systems and supplied as a single piece. Made in Poland, this coupling joins sections of irrigation tubing to maintain a sealed flow path and enable reliable water distribution in garden and landscape drip irrigation installations. The connector fits standard thin-wall hoses with nominal diameters of 1/2" or 5/8" and features internal profiling for secure attachment. The part is finished in a white‑grey color and is intended for use where a compact, straightforward coupling is required to repair or extend drip lines.

Advantages

The coupling provides a quick and simple method to connect two lengths of drip irrigation hose without adhesive or complex tools. Well profiled internal teeth improve grip on thin wall hoses, reducing the risk of slippage under normal working pressure. Its compatibility with standard 1/2" or 5/8" hoses makes it versatile for common garden and landscape systems. As a single-piece accessory produced in Poland, it offers consistent dimensional quality and a neutral white‑grey finish for unobtrusive installation.

Suitable for

• Repairing a damaged section of 1/2" or 5/8" thin-wall drip irrigation hose
• Extending existing drip lines in garden beds, borders, and containers
• Connecting short hose runs when installing or modifying low-pressure drip systems
• Temporary or permanent joins where a compact coupling is preferred

Key specifications

• Compatible hose diameters: nominal 1/2" or 5/8" (thin-wall drip tubing)
• Material: durable plastic suitable for outdoor irrigation use
• Color: white‑grey finish
• Connection type: insert coupling with internal profiled teeth for grip
• Supply: single piece per pack
• Manufacturing origin: Poland

How to use

Ensure hose ends are cut square and free of debris before assembly. Push each hose end firmly onto the coupling until it seats against the internal stop; the profiled teeth will bite into the thin-wall tubing to create a mechanical seal. For improved sealing, insert hose ends evenly and, if needed, use hose clamps or spiral binders compatible with thin-wall tubing to increase retention under higher pressure. Avoid twisting the hose during insertion to maintain an aligned flow path.

Usage recommendations

For long-term installations, verify hose compatibility by testing a single coupling under working pressure and consider using external clamps in exposed or high-pressure segments. Store spare couplings in a shaded, dry place to preserve material properties.
