Two Little Fishies Ball Valves are great for regulating water flow through standard hose used for devices such as canister filters, pump return lines, protein skimmers, calcium reactors, etc. Hose slips onto barbed end for secure fit in 1/2 inch, 5/8 inch, 3/4 inch and 1 inch I.D. tubing. The MPT (male pipe thread) x Hose barb fittings are great for other applications that require a solid connection on on end of the fitting to flexable tubing on the hose barb fitting.
