The thread is NPT 1/2, Please check the Thread. We have received some refund customers that marked the thread wrong thing, actually they don't understand the NPT Thread is the pipe thread standard in North America, and it is not equal to 1/2" of the inner diameters you measure it directly. Please check the thread carefully. As customers requirements, we update the coating from Zn to Zn-Ni alloy, this coating would be better performance and we keep the same price.
