4" PVC 5 way (aka side outlet cross). Top port is FPT (female pipe thread), the other 4 are standard slip socket. This is a 2 piece constructed fitting. Good for construction projects, not good for plumbing projects. Not a flow through fitting, not an NSF fitting. Now comes with ALL STAINLESS STEEL nuts, washers and bolt thru the center for extra strength. These are custom made items, made for just your order. There is no return on these items and it may take extra time to complete your order.
