The A. M. Leonard brass quick coupler hose connectors--male and female--are great, full-flow connectors. I've bought several for use around my 17 1/2 acre property. I am planting an arboretum--at least that's what I choose to call it--of rare and unusual cultivars of native trees and shrubs. Most of these plants, even though they are within sight of our house, are far enough away that I have to connect 2 to 4 75-foot 3/4 inch internal diameter hoses to reach them. These quick connectors work great to couple these hoses, watering wand, and similar attachments. Other connectors--even the brass ones--did not do nearly as well. I like the fact that these connectors do not restrict the water flow and I have no trouble watering my cherished native plant cultivars. Make sure you buy enough for the attachments in addition to connecting hoses; you won't regret it.
