16 mm Lock-Ring Tee with 1/2-Inch Male Takeoff

This 16 mm lock-ring tee connects two drip line ends to a central 1/2-inch male-threaded takeoff. The two opposite ends continue the line through the junction, while the threaded branch provides a separate connection to a matching female fitting. It is a three-way connector for an irrigation layout that needs a threaded supply or branch point.

Understand the three connections

• First line connection: 16 mm with a retaining ring.
• Central branch: 1/2-inch male thread.
• Second line connection: 16 mm with a retaining ring.

The blue rings retain the line at the side inserts. The central male connection screws into a compatible female fitting; it does not accept a push-on drip line. Confirm the mating thread standard and the line dimensions before ordering, since a half-inch label alone does not establish compatibility with every female fitting.

Position the tee in your irrigation layout

Use the straight connections for the two line sections and place the threaded branch where it can connect without bending or pulling the lines. Leave enough room to seat each line fully and move its retaining ring. Support the surrounding pipework so that the tee does not carry unnecessary strain from a heavy fitting or an unsupported supply line.

Fit and test each joint

Turn off the supply and release the pressure before installation. Cut the line ends square, keep the connection surfaces clean, and seat both ends fully before securing the rings. Engage the threaded fitting carefully and use the sealing method appropriate to its confirmed thread type. Avoid overtightening the plastic connection. Restore water gradually and inspect all three joints for leaks during the first irrigation run.

Sold as one tee. Drip line, female-threaded adapters and sealing materials are separate installation items.
