Schedule 40 usually white, this is a wall thickness of PVC. Pipe and fittings can come in various “schedules” or wall thicknesses. This is the most commonly used thickness for home projects and irrigation.
Schedule 80 usually gray in color, schedule 80 PVC pipe and fittings have a thicker wall than schedule 40 PVC. This makes sch 80 able to withstand higher pressures. Sch 80 PVC is commonly used for commercial and industrial purposes.
