How To Connect Galvanized Pipe To PVC Pipe

• Galvanized pipe is produced from a metallic material. 
• Whereas PVC piping is produced from plastic material.
• GI piping uses the threaded tightening method to connect another GI pipe.
• Whereas PVC piping uses the glue method to connect another PVC pipe.

• Since PVC piping is using non-threaded glue method to connect the other piping. 
  
• The PVC piping needs to be converted into a threaded ended adapter beforehand.
  
• PVC PT socket with female threaded or PVC valve socket with male threaded is designed to glue the PVC ending for becoming a threaded adapter.
  
• Once the PVC piping ending has become a threaded adapter, then it is ready to be tightened onto the galvanized threaded fitting material.
