20 mm / 25 mm Barbed Start Connector for Irrigation Laterals

This barbed start connector provides the start of an irrigation lateral at a compatible supply connection. Choose the listed 20 mm or 25 mm option to match your branch line, then check the supply-side opening and sealing arrangement separately.

A compact start for a branch line

The connector has a straight black body, barbed connection profiles and a central flange. Its role is to establish a branch connection rather than join two lengths of tubing as an ordinary inline coupler. The inlet and lateral connection must each suit the intended installation.

Choose the branch size

• Available options: 20 mm or 25 mm.
• Function: start an irrigation lateral.
• Installation checks: tubing fit, supply opening and compatible seal.

The selected branch size does not specify the hole diameter for every header or supply line. Match the fitting, supply material and sealing components before preparing an opening. Do not assume that a seal intended for a different starter will fit this connector.

Prepare the supply connection

Shut off and drain the supply before installation. Use the opening dimensions and seal arrangement specified for your fitting assembly. Remove debris from the opening and check that the surrounding pipe is sound. Seat the supply connection correctly, then push compatible lateral tubing fully onto its barbed end.

Keep the new lateral supported close to its start so its weight or movement does not pull on the supply connection. Flush the line as needed, restore water gradually and inspect the inlet and tubing joint under flow.

Check fit before repeating the installation

For several laterals, confirm one complete connection before preparing the remaining openings. A correct branch size still needs a matched inlet and seal. Browse drip fittings for the other connections required along the line.
