Aluminum Nozzle Coupling with 2″ Contractor (50mm) Threads




The Aluminum Nozzle Coupling with Contractor Threads features 50mm or 2″ contractor threads.  These couplings are made from lightweight aluminum alloy.  They are extremely resilient and therefore, ideal for projects where there is the possibility of damage. Each nozzle coupling comes with a compatible washer 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!
