Locking Pipe Coupler Valve — 16 mm or 20 mm

A locking pipe coupler valve joins two matching PE irrigation pipe ends and adds a manual shutoff at the joint. It is useful where an individual lateral needs to be opened or closed without disconnecting the pipe. Select the 16 × 16 mm or 20 × 20 mm option to match both ends of the existing line.

Two pipe connections and one control point

The straight body has a pipe insert and retaining nut at each end. The hand-operated handle sits above the central valve body, keeping the control accessible after installation. This arrangement combines an inline coupling with a local shutoff, so a separate coupling and valve are not needed at that same joint.

Choose the pipe size before fitting

• 16 × 16 mm: equal-size connection for a 16 mm line.
• 20 × 20 mm: equal-size connection for a 20 mm line.
• Both options use pipe ends rather than a male or female threaded outlet.

Check the line dimensions and pipe construction before ordering. A nominal size on another fitting does not establish compatibility with this connection. Drip tape and round PE pipe can require different retaining arrangements even when their size labels look similar.

Install and inspect the joint

Stop the water supply and release pressure before cutting the line. Make clean, square pipe ends, seat them fully on the inserts, and secure the retaining nuts without distorting the pipe. Leave clearance around the handle for operation. Restore the supply gradually and check both joints during the first watering run. When servicing the line, shut off the supply and release trapped pressure before loosening a connection.

Sold as one valve in the selected size. Pipe, threaded adapters and other installation components are supplied separately.
