This is a CT-8 Nozzle has a 1/2” nozzle orifice and measures 1 3/4" in length. It has 3/4” mounting thread with a 1/2” entry and durable metal jacket with straight, barrel-shaped nozzles.
These nozzles are lined with durable tungsten carbide and are for hoses with a 1/2” ID. A hose with a 1/2” ID requires a 1/2” entry nozzle paired with a nozzle holder to accommodate the 1 3/16” OD of the hose. Your purchase of this nozzle includes an NW-1 Washer.
NOTE: When your nozzle orifice goes up one size, or wears 1/16” past its original size, it’s time for a replacement.
