Duckbill Layflat Hose Tee with Lock-Nut Ends, 16 or 20 mm

A duckbill takeoff for two irrigation runs

The duckbill layflat hose tee combines a central hose takeoff with two opposing lock-nut line connections. Its upper assembly has a projecting duckbill-shaped lip and a ribbed upright body. The two blue nuts retain matching irrigation lines on either side of the black tee. This gives you a single takeoff point for arranging runs in opposite directions from a supply hose.

Choose the correct takeoff style

The available selections are 16 mm and 20 mm for the irrigation line ends. These sizes do not specify the hose mounting hole or the supply hose diameter. Compare the projecting lip, upright body and mounting arrangement with the fitting your layflat hose is designed to accept. The duckbill profile distinguishes this version from a flanged hose tee, so check the complete interface rather than ordering only by line size. Confirm the hose material and wall construction before preparing the takeoff.

Keep the hose joint accessible

Plan the two runs so both leave the tee freely, with enough support to avoid pulling the upright assembly sideways. Follow the mounting method suitable for the matched hose and duckbill takeoff. Prepare clean line ends, seat them fully and secure each retaining nut. Bring water into the system gradually while observing the hose contact area and the two line connections. Stop the water if any seepage appears, then check the seating and alignment before further adjustment. Leave the fitting accessible for inspection after hose movement, and examine the joint again when the irrigation layout is changed.
