This reducing adapter is a stainless steel 304 pipe fitting with 3/8 inch male National Pipe Taper (NPT) threads on one end and 1/2 inch female NPT threads on the other end for connecting two pipes of different sizes. The adapter has NPT threads for creating a tighter seal than straight threads and a hexagonal shape for increased leverage and use with a wrench during installation and disassembly. It is made from stainless steel 304 for resistance to chloride corrosion and greater corrosion resistance than stainless steel 302.
