Adjustable irrigation sprinklers for 4.6mm irrigation hose

Adjustable sprinklers for 4.6mm (3/16") hose.  The flow through the sprinkler may be adjusted by twisting the cap. Multiple sprinklers may be places in series using the provided tee.

The sprinklers uses a 2.4 x 18 mm O-rings to reduce leakage through the threads.
It may be used without if there is sufficient water pressure. My setup is gravity feed and need the o-rings to keep the pressure up. 

The sprinklers are connected to the hose by a small angle/tee connector with integrated pegs.

Adapters from ½ “ garden hose to 3/16”/4.6 mm Gardena micro drip hose are included.
