This versatile riser can be used to adapt your garden sprinklers to suit your needs. Either attach directly into 1/2 poly tubing with a 1/4" barb or to 1/4" poly tubing inserted into an equipped riser stake. Chose from various Olson Ultra-Jet, O-Jet and Micro-sprayers to suit the shape, volume and diameter required. Can also be used with the built-in internal barb on Olson mini-sprinklers.
