PVC Schedule 80 is offered in case quantities only.
CPVC Schedule 80 is gray and is commonly used for plumbing and drainage. CPVC Schedule 80 is similar to regular Schedule 80 however, CPVC 80 has a higher temperature range. CPVC can be used for applications up to 200°F/93°C. PVC Schedule 80 has the same outside dimensions of PVC 40 but has a thicker wall - therefore making the inside dimensions slightly smaller. PVC 80 is generally used when there is a need for a stronger pipe compared to PVC 40.
