Thank you for asking help from the PlumbersStock team! This General Wire & Spring JN-0 is a nozzle set designed for a 1/8-inch hose used in JM-1000 & JM-1450 jet sets. According to page 4 of this General J-1450 Operator's Manual, a 1/8" hose will connect to a 1-1/2" to 2" pipe. It is also mentioned that 1/8-inch hoses may be connected directly to the accessory outlet if an adapter fitting(AD-1 or AD-2) is used between the hose and quick connect. Adapters may be ordered separately by contacting one of our customer service representatives at 435-868-4020 between 8:00 AM and 7:00 PM MT or through e-mail at email@example.com. If you need more technical instructions, it would be best to call the manufacturer at 800-245-6200. Thank you for visiting PlumbersStock.com!
