The Brass Nozzle Coupling features 50mm or 2″ contractor threads. These are made from a moderately strong and tough brass with corrosion resistance and ductility. Rated for 175PSI. They are extremely resilient and therefore, ideal for projects where there is the possibility of damage. You’ll also hear these called a blast nozzle holder. Each nozzle coupling comes with screws for quick assembly. Match your coupling with the correct size hose by the drop down menu. We use the OD so there are no mistakes!
