These brass ball valves have steel made, quarter-turn lever handles to allow positive stop action for full shut-off, and PTFE seals for leak-proof operation. Selected models have nylon covered steel handles. Choose from a wide range of ball valves, available in solder to solder, male to female, and female to female types.
