20 mm Locking Drip Tape Coupler Valve

A 20 mm locking drip tape coupler valve joins two matching tape ends and provides a manual shutoff between them. Use it at an inline joint where a drip row needs its own control point. The selected connection is 20 mm on both sides, with retaining nuts to secure the tape ends.

Control a row at its inline connection

The valve has a compact central body, a hand-operated handle and a tape connection at each end. Closing the valve interrupts water passing through that joint. This makes the control useful for a row that needs to be taken out of service while planning maintenance or changes to the irrigation layout. Always release the supply pressure before opening a connection.

Match the tape to the connection

• Connection size: 20 mm.
• Connection arrangement: tape to tape, in a straight line.
• Retention: a locking nut at each end.
• Operation: manual handle above the valve body.

Confirm the tape diameter and wall construction before installation. A 5/8-inch or 16 mm tape fitting is a different connection size and should not be selected as a replacement for this 20 mm valve. Round PE pipe and drip tape also require different compatibility checks, even where nominal dimensions appear close.

Install without straining the tape

Stop the supply, release trapped pressure and prepare clean, square tape ends. Seat each end fully on its insert and secure the locking nut without folding or damaging the tape. Align the run so the joint is not pulled sideways, and leave the handle accessible. Open the water supply gradually, inspect both ends for leakage and recheck the joint after the first watering run.

Sold as one 20 mm valve. Drip tape and other irrigation fittings are separate items.
