Sch 80 CPVC Fittings

Schedule 80 CPVC fittings are used to securely link together different sections of schedule 80 CPVC pipe. Due to high temperature rating, schedule 80 CPVC fittings are commonly used in applications where hot fluids are being transported, such as in chemical processing, water distribution, fire suppression systems, and plating. Additionally, schedule 80 CPVC is corrosion resistant, so these fittings are also used in pipe systems that are capable of handling most types of acids, salts, bases, oxidants, and other corrosive liquids.

PVC and CPVC may look similar, but there is a crucial difference – while CPVC is made up of the same basic elements as PVC, it undergoes chlorination. By undergoing a free radical chlorination reaction, portions of hydrogen are removed and replaced with chlorine. The added chlorine is what allows schedule 80 CPVC to handle higher temperatures.

Temperatures above 140⁰ F can weaken and soften PVC, which is problematic, especially for industrial and commercial applications, where higher temperatures are more common. CPVC, however, is capable of enduring temperatures up to 200⁰ F. In fact, building codes for industrial and commercial applications usually require the use of CPVC.

Schedule 80 refers to the thickness of the pipe, and CPVC refers to the chemical makeup of the pipe. What does that mean for you? Not only does the CPVC boost temperature-handling capabilities, the schedule 80 thickness means about to tolerate higher PSI levels (the same as schedule 80 PVC). Schedule CPVC is the strongest type of PVC available. It combines the PSI handling of schedule 80 and adds the toughness of CPVC.

Schedule 80 CPVC fittings end types can be slip, spigot, or threaded. Slip ends are also referred to as socket ends and are named “slip” ends because they slip over the end of a pipe. They are usually abbreviated with the letter S. Since they are smooth, they require the use of adhesive. Spigot ends also require the use of an adhesive. They are smooth, but fit into a pipe or other fitting instead of slipping over it. Threaded ends are either male threaded (MIPT/MPT) or female threaded (FIPT/FPT). When threading is on the outer section of the fitting, the fitting is male threaded and screws into a pipe or another fitting. When the threading is on the inner section of the fitting, the fitting is female threaded, and the pipe or other fitting screws into it.

Some of the other key features of CPVC fittings include:

  • Durable and dependable, even in the toughest applications
  • Capable of handling high pressure and high temperatures (up to 200⁰ F)
  • Same sizing system as standard schedule 40 and schedule 80 PVC fittings
