Lock-Nut 90-Degree Elbow — 16 mm or 20 mm

A lock-nut 90-degree elbow redirects a drip line at a right-angle corner. Its two line connections use retaining nuts, so both ends can be secured after the line is seated on the inserts. Choose the 16 mm or 20 mm version to match the two line sections.

Two secured ends at a right-angle bend

The view shows the black elbow body, two blue retaining nuts and the projecting line inserts. Both legs turn through the same corner, with a separate nut at each end. Leave room around these nuts when positioning the fitting so they can be reached during installation and servicing.

Connection details

• Connection options: 16 mm or 20 mm.
• Geometry: 90-degree elbow.
• Line retention: one locking nut on each leg.

Choose and position the fitting

Match both line ends to the selected connection size. Check the actual line dimensions and wall construction before fitting; a nominal diameter alone does not establish compatibility with every tape or tubing product. Lay out the corner so the line approaches each leg without pulling sideways or forming a sharp fold beside the joint.

Fit and inspect the joints

Stop the supply and release pressure before cutting the line. Prepare clean, square ends and seat each end fully on its insert. Secure the retaining nuts without crushing or twisting the line. Restore water gradually and inspect both joints during the first watering cycle. If a connection needs attention, release pressure again before loosening its nut.

Sold as one fitting. Line, mating components and installation accessories are separate.
