16 / 20 mm Drip Line Flush Valve with Lock Connection

A drip line flush valve with a lock connection provides a flushing outlet at a compatible tubing end. Choose the listed 16 mm or 20 mm option for your line, and check the tubing dimensions before installation.

Connect directly to a compatible tubing end

This version uses a tubing connection rather than a male or female threaded inlet. The black insert and blue locking collar sit behind the ribbed blue outlet cap. Match the line to the insert and collar assembly; a nominal size alone does not establish compatibility with every tube or tape wall.

Leave space around the flushing outlet

Keep the outlet visible and accessible at the line end. The installed 16 mm example shows the collar behind the blue cap, with the connected tubing supported along the ground. Position your discharge so flushing water does not run onto nearby equipment.

Choose and fit the connection

• Listed options: 16 mm or 20 mm.
• Inlet style: tubing insert with a locking collar.
• Use: flushing outlet at a drip line end.

Turn off and depressurize the line before working. Cut the tube cleanly, remove dirt and seat the compatible end fully on the insert. Secure the collar without damaging the tube. Restore water gradually and check the tubing joint and outlet.

Inspect the insert and collar

The two pictured views show the 16 mm connection from different angles. Check that the line sits properly on the insert and remains supported after fitting. These photographs illustrate the 16 mm version; select the 20 mm option only after checking the dimensions of your own line.

Maintain the line end

Include the valve in regular flushing inspections and follow the operating instructions for the fitted assembly. Compare drip fittings when planning the rest of the line.
