16 mm Barbed Starter Connector with Grommet

This 16 mm barbed starter connector comes with a separate matching grommet for the supply connection. The black connector has a barbed branch end, a central stop and a projecting inlet that works with the seal. Each listed option is one connector-and-grommet set for starting a compatible branch.

Fit the supply seal and branch

The grommet forms part of the inlet assembly, while the barbed outlet connects to the branch tubing. Confirm the supply material, wall thickness and opening size against the actual seal before drilling or punching. A 16 mm branch size does not automatically mean a 16 mm installation hole. Check the tubing inside diameter against the barb separately.

Check the tubing before fitting

Compare the selected connection size with the tubing inside diameter and check that the tubing type is suitable for a barbed joint. A nominal size printed on a tube may describe another measurement, so verify the actual fit rather than relying on the label alone. Inspect the cut ends and remove any section that is split, distorted or damaged.

Install and inspect the assembly

Turn off the water supply and release pressure before working on the line. Make clean, square cuts where needed and keep dirt out of the open tubing. Seat each compatible connection fully without twisting the finished assembly out of position. If your tubing system calls for additional retention, use the appropriate matching hardware.

Restore water gradually and inspect every new joint for seepage or movement. Check again during the first watering cycle, especially after repositioning the line. Isolate the supply before correcting a loose connection. Confirm the pressure and temperature limits of the complete tubing system before putting it into regular service.
