16 mm Lock-Nut Tee with Barbed Pipe Takeoff

This 16 mm lock-nut tee provides two opposite line connections and a barbed pipe takeoff at the center. The straight connections use retaining nuts, while the branch has a push-in barb. Use it where a drip line junction needs a separate connection to compatible irrigation pipe.

Check all three connection points

The view shows two blue locking nuts on the straight run and a black barbed branch at a right angle. The branch does not use the same retaining arrangement as the two side connections. Identify its actual fit before assembly rather than assuming that all three ends accept the same line.

Connection details

• Listed line connection size: 16 mm.
• Straight connections: two locking-nut ends.
• Center connection: barbed pipe takeoff.

Choose and position the fitting

Confirm the dimensions of both line sections and the branch connection before installation. The listed 16 mm option does not establish the branch pipe dimensions by itself. Check actual fit and wall construction, then position the tee so the three lines can approach without bending sharply or pulling on the body. Leave clearance around both locking nuts.

Fit and inspect the joints

Stop the supply and release trapped pressure. Cut clean, square line ends and keep the insert surfaces free from dirt. Seat the two straight connections fully and secure their blue nuts without twisting the line. Fit the branch to compatible pipe and use the retention appropriate to that pipe. Support the surrounding runs, restore water gradually and inspect all three joints during the first irrigation cycle.

Sold as one fitting. Line, mating components and installation accessories are separate.
