Fountain Nozzle Kit (FT-03) We recommend using FT-300 pump, but 250 or 300 will work Comes with 2 nozzles, a Bell nozzle and Multi Tier Blossom nozzle. Nozzles can directly fit over 1/2" outer diameter connections, and fit into 5/8" inner diameter connections. Features an extension that adjusts from 6" to 10 1/2" in height. Top of extension accepts the nozzles, and bottom of extension has a 3/4" threading that screws into another piece. In between the pump and extension is a piece that features an adjustable nozzle flow restrictor, and an adjustable water flow diverter; this piece screws into a 3/4" threading, and has a flow diverter that accepts 3/4" outer diameter tubing (has threading inside). Also featured is an adapter that allows you to connect the 3/4" threading, of the extension and middle piece, to a pump that accepts 7/8" threading. Blossom nozzle can be adjusted as the inside is threaded. Works well with our FT-250 and 300 Fountain Tech pumps.
