Male quick release coupling
Stilo drinks system helmet kit for ST4 & ST5 helmets. Included in this pack is a male coupling, tube and rubber bite valve. The coupling assembly is designed to allow the driver a quick evacuation so that in case of emergency, by just a slight tug, the coupling slips off releasing the driver. All pipes are fitted to the helmet internally.
