                                                                All Needle Valves are assembled with silicone free lubricant and have an FPM O-Ring and a PTFE seat.
 Hayward Needle Valves are used for accurate metering of fluids. Turning the thumbwheel moves a tapered piston into the PTFE seat to control the flow down to a few drops per minute. Precision molded, fine pitched stem threads permit this very fine metering flow control.   007
