This Schedule 80 PVC pipe is engineered for demanding industrial and high-pressure applications where reliability is paramount. With precise dimensions of 1-1/4 inch nominal diameter, 1.66 inch outer diameter (OD), and 1.278 inch inner diameter (ID), this heavy-duty pipe features thicker walls than standard options for enhanced durability and pressure handling capabilities. The robust construction makes it ideal for industrial process lines, chemical transfer, and other high-pressure systems. The pipe's thick walls provide excellent structural integrity while maintaining smooth flow characteristics through the precisely sized inner diameter. Perfect for professional contractors and industrial applications where standard Schedule 40 PVC isn't sufficient for the pressure requirements. This industrial-grade PVC pipe delivers the performance needed for critical fluid handling systems while offering the corrosion resistance and long service life characteristic of quality PVC materials.
