Positioned Lock-Nut Takeoff for 16 mm Drip Tape

Inspect the connection shape

This positioned lock-nut takeoff starts a 16 mm drip-tape branch from a compatible prepared header. Its body has a larger blue locking nut at the tape end, a smaller blue nut toward the header end and a black central positioning section. The two ends serve different connection roles; inspect both before assembly.

Check the tape and header separately

• Listed branch connection: 16 mm.
• Match the tape wall and end fit to the locking connection.
• Confirm the header opening and sealing arrangement before drilling.

The branch diameter does not specify the hole required in the header. Check the header material, wall thickness and fitting seat together before making an opening. An opening that is too large or has a damaged edge may prevent the takeoff from seating correctly. Do not assume that another start connector uses the same hole size.

Assemble the branch

Work with the irrigation supply turned off and depressurized. Make a clean opening using the confirmed installation dimensions, clear any loose debris and position the header-side connection squarely. Prepare a clean, square tape end, seat it fully on the compatible outlet and secure the locking nut without twisting or tearing the tape.

Check under flow

Support the new branch so pulling on the tape does not load the header connection. Flush the line before regular watering, then restore flow gradually and inspect both ends for seepage or movement. If either joint needs correction, stop the supply first. Keep the area accessible for future inspection and avoid burying an unchecked joint beneath mulch or soil. This fitting provides a branch connection; use a separate compatible valve wherever individual branch shutoff is required.
