The Contracor NTC Short Venturi Nozzle is a nozzle with a tungsten carbide core and an aluminum jacket. The short 45mm in length design makes it easier for applications with limited blasting space, at the cost of some performance compared to regular venturi nozzles. With a service life of up to 400 hours, the Contracor NTC Short Venturi Nozzle is a great choice for those who demand a good quality low cost short nozzle. The nozzle fits 19mm (¾") thread nozzle holders.
