10 ml syringe adapter
This adapter is meant to make it easier to connect hydraulic systems to toys and models such as these Open Ended Hydraulic Toys and the Hydraulic Judo Bots by LanceMakes. This eliminates the need to glue the cube with the hole on the end of the syringe, allowing you to attach the end with a zip tie.
