This nylon fog nozzle has a hose tail for 1" hose. It fits directly into the hose end, providing a fog nozzle without a separate threaded nozzle connection. The red body and black outlet surround match the stocked hose-tail design.
Push the hose over the tail and secure it with a hose clamp. The 1" connection refers to the hose bore, rather than a female pipe thread.
The hose-tail design is distinct from the small and large female-threaded Powerjet nozzles. Water delivery depends on the supply pressure and the hose feeding the nozzle.
