This quarter circle Microspray is machined in brass and provides a useful directional spray.  Also used where plants have been masked or missed from the main spray.  The quarter circle sprays reach 1.2 metres (4').  You fit these to the ends of 5mm Microspray Stems  which come in three heights: 20cm (8"), 30cm (12"), and 45cm (18"),  Also see: Microspray Stems.

First screw the Microspray into the top of the stem.  Dipping the top of the stem into a mug of very hot water prior to assembly helps.

Lay out the 13mm Polytube where you want it to run.  Punch a small hole in the top of the tube using our Hole Punch, then screw in the Microspray stem.  There is a small flange on the stem to stop you going too far.  Then bury the tube to about 5cm (2") to hold the stem upright.
