Product Information

Full details

The HydroSure Double Barbed Fittings are designed for DIY gardeners and professional landscapers looking to establish reliable, leak-free irrigation systems using 18mm LDPE or drip line tubing. These connectors provide an essential link for extending or repairing garden and greenhouse watering networks with a secure, double-barbed locking mechanism. While they offer exceptional durability and UV resistance, users should note that they are specifically engineered for 18mm tubing and may not be compatible with non-standard pipe sizes without additional adapters.

FAQs

Are these fittings compatible with 16mm tubing?

No, these are specifically designed for 18mm LDPE or drip line tubing and will not provide a secure, leak-free seal on 16mm pipe.

Do I need to use Jubilee clips or glue to hold these in place?

No, the double-barbed design is engineered to lock into the tubing securely without the need for additional adhesives or mechanical clips.

Can these be left outside all year round?

Yes, the fittings are constructed from UV-resistant material designed to withstand year-round outdoor exposure.

What is the primary material used in these fittings?

They are made from high-grade, durable, UV-stabilized plastic.

Can I use these for pressurized main water lines?

These are intended for standard garden irrigation systems; they are not rated for high-pressure municipal water mains or indoor plumbing.

Troubleshooting

Tubing is too hard to push onto the barb

Soften the tip of the tubing in warm water for 30 seconds to increase flexibility before insertion.

Visible leaking at the connection point

Ensure the tubing was cut squarely and pushed fully past both sets of barbs; check for tears or debris inside the pipe end.

Pros and Cons

Pros

Provides a highly secure, leak-proof connection for irrigation lines
UV-resistant material ensures long-term outdoor performance
Simple push-fit installation requires no specialized plumbing tools
Versatile application for both home garden systems and professional greenhouses

Cons

Not intended for use with hard PVC pipes or rigid plumbing systems
Size is specific to 18mm tubing, limiting use with smaller or larger pipe diameters
May require significant force when inserting into cold, stiff tubing

Setup, Compatibility & Care

To install, ensure your 18mm LDPE or drip line is cut cleanly. If the tubing is cold and stiff, dip the end into warm water for 30 seconds to soften the plastic, making it easier to slide over the barbs. Push the tubing firmly onto the fitting until it passes over both sets of barbs. No glue is required for these fittings. To clean or maintain, simply disconnect the tubing and rinse the fitting under water to remove sediment buildup. Avoid using harsh chemical cleaners, as these can degrade the plastic structure over time.
