MTM Hydro's Garden Hose Fittings and Filters offer an exceptional solution to keeping your water intake free of debris and adaptable for nearly any pump. Standard Garden Hose connections are always 3/4" while the adapter side of a garden hose fitting will vary upon need for the connection point. Upon installation, this particular item has a spring that supplies pressure to the nut and ensures a firm seal when the garden hose is screwed in. By lightly compressing the nut you will gain access to the 3/4" threads to install your garden hose.
