16 mm Lock-Ring Start Connector for Drip Headers

Build a secure irrigation connection

A lock-ring start connector provides the transition from a prepared header outlet to a drip branch. The branch end has a retaining ring, while the inlet end has an insert and stop. Use it to build or replace the start of a row with a sealing arrangement matched to the header.

Choose the correct fit

The 16 mm dimension describes the branch connection, not the hole to drill in the header. Confirm inlet fit, header wall and required sealing component before preparing an opening. A seal or grommet, header pipe and branch line are separate components unless explicitly included in the selected option.

Available connection sizes

16 mm branch connection. Select the required option when ordering. Supplied as one selected fitting.

Install and check the joint

Prepare the header outlet to the dimensions required by the matched seal and inlet. Remove debris, install the seal correctly and seat the connector without twisting the header wall. Cut the branch square, seat it fully and secure the retaining ring.

Run water through the assembled line and inspect both connection points during the first irrigation cycle. Stop the supply before adjusting a joint. Use the fitting within the operating limits of the matched line and system components; no pressure rating is specified for this item.

Common questions

Does this control water flow?

There is no shutoff handle. If each row needs independent flow control, choose a suitable start valve or add a compatible valve to the branch.

What should I check before buying?

Confirm the connection size, mating line type and sufficient access to seat and secure the fitting. Replace torn or distorted line ends before assembling the joint.
