Hi, I need to connect a 4" cast iron valve to PVC pipe. The cast iron valve has ASME class 125 flanges at both ends. I was thinking of using a PVC NPT TOE nipple and PVC coupling to connect the PVC pipe to the cast iron flange (C.I. flange > PVC nipple > PVC coupling > PVC pipe). Is it okay to thread PVC into cast iron?
