Swivel Nut and Stem – 3/8 Inch Barb x 3/8 Inch FFL

A swivel nut and stem set with a 3/8-inch hose barb and a 3/8-inch female flare (FFL) connection. Made with a stainless steel stem and chrome-plated brass nut. The nut turns independently of the stem to help avoid twisting the tubing when connecting to a matching male flare fitting.
