Product Information

Full details

The AP Supplies Micro Tee Connector is designed for home gardeners, landscape enthusiasts, and greenhouse managers who need a reliable way to split water lines in low-pressure micro irrigation systems. Its key benefit is a leak-proof, secure connection that ensures consistent water distribution to multiple plant zones using 4.5mm micro tubing; however, note that it is specifically engineered for low-pressure systems and should not be used in high-pressure main lines.

Extended Product Information

FAQs

Are these connectors compatible with 6mm tubing?

No, these are specifically sized for 4.5mm tubing and will likely leak or fail if used with larger 6mm lines.

Do I need glue to keep the tubing on?

No, these are designed as push-fit barbs. The ridges on the connector are intended to provide a mechanical seal without adhesives.

Can I use these for indoor hydroponics?

Yes, they are excellent for indoor setups as long as the water pressure is within the typical range for drip irrigation.

How many come in a pack?

This product comes in a convenient 10-pack, which is ideal for small to mid-sized irrigation projects.

Will these degrade in the sun?

They are made with UV-resistant materials specifically to prevent degradation from sun exposure in outdoor gardens.

What is the maximum pressure these can handle?

These are intended for low-pressure micro irrigation systems. Always check your specific pump pressure to ensure it does not exceed the limit of your tubing.

Troubleshooting

Tubing is hard to push onto the barb

Soak the end of the micro tubing in warm water for 30 to 60 seconds to soften the plastic.

Water leaking at the connection point

Ensure the tubing is cut squarely and pushed past all ridges on the barb. If it continues to leak, trim the end of the tubing and re-seat it.

Tubing pops off the fitting

The line pressure may be too high. Ensure you are using a pressure regulator at the water source to keep the system within low-pressure specifications.

Pros and Cons

Pros

  • Durable, UV-resistant construction
  • Tight, leak-proof fit for standard 4.5mm tubing
  • Simple, tool-free installation process
  • Ideal for complex micro irrigation layouts

Cons

  • Not suitable for high-pressure irrigation systems
  • Limited to 4.5mm tubing sizes
  • Can be difficult to remove once fully seated

Setup, Compatibility & Care

To set up your irrigation system, first ensure your main supply line is clear of debris. Use a sharp pair of scissors to cut your 4.5mm tubing cleanly. If the tubing is stiff due to cold weather, soak the ends in warm water for 30 seconds to make them more pliable before pushing them onto the barb. For maintenance, inspect the connections at the start of each growing season. If a connection feels loose, trim a small section of the tubing and reconnect it to expose fresh material. The connectors themselves are weatherproof, so they can remain in place throughout winter, though you should drain the lines to prevent freezing damage.
