Drip Irrigation Lock-Nut Elbow with 1/2-Inch Male Thread

Make a right-angle transition between an irrigation tube and a female-threaded fitting. This elbow places a lock-nut tube connection on one leg and a 1/2-inch male thread on the other. It lets the lateral approach a threaded component without forcing the tube into a tight bend immediately beside the joint.

Choose the tube end

Select the 16 mm or 20 mm tube option to match the actual line you are connecting. Both listed options have a 1/2-inch male threaded end; choosing the larger tube connection does not enlarge the thread. Compare the tube's outside diameter and wall construction with the fitting before purchase. A nominal size does not guarantee compatibility with every drip line or hose.

Check the threaded connection

Pair the male end with a compatible female port. Confirm the thread standard and the sealing method required by the mating part before installation; the 1/2-inch designation alone does not tell you whether a separate washer, gasket or thread seal is needed. Do not force mismatched threads together.

Install without stressing the corner

Shut off the water and release pressure first. Align the elbow with the planned route, seat the tube fully on the insert and tighten the blue lock nut by hand. Support the nearby tubing and keep enough clearance to inspect the threaded joint. Restore the water gradually and check both connections for leaks.

Sold as one elbow fitting. Tubing, the mating female-threaded part and any sealing accessory are separate.
