PVC and CPVC Plumbing Ball Valves and Fittings

Pipes, valves, and fittings make up the heart of plumbing as their purpose is to guide fluids from point A to point B within a building or home. The longevity of the plumbing system itself relies on a number of factors, one being the type of material the parts are made out of. By selecting the appropriate material, whether steel, copper, stainless steel, PVC, CPVC, or aluminum, fluid within the system stays contained and the system itself works more efficiently.

PVC (polyvinyl chloride) or CPVC (chlorinated polyvinyl chloride) is a popular choice for plumbing ball valves and fittings. These materials are selected due to their ability to withstand high temperatures and for the fact that they’re designed for both hot and cold-water systems. PVC and CPVC connections are CTS (copper tube size), which is a much smaller pipe size than IPS (iron pipe size). Overall, PVC and CPVC are also versatile as they can be used on residential, commercial, and industrial applications.

While PVC and CPVC are very similar, certain applications may require the use of one material over the other. Continue reading to learn the difference between the two:




  • Typically contains 75% hydrogen and 25% chlorine
  • Can handle temperatures up to 140°F
  • Often used for unheated water as well as for vent and drainage
  • Considered more economical than CPVC
  • Typically contains 60% hydrogen and 40% chlorine
  • Can handle temperatures up to 200ºF
  • Widely used for both hot and cold potable water applications
  • Harder than PVC, making it more prone to breaking or cracking, but is also more flexible than PVC


When it comes to installing PVC and CVPC plumbing ball valves and fittings, the plumber has multiple joining methods to choose from, such as the ones listed below:

  • Solvent cementing – Uses solvent end connections
  • Threading – Uses MNPT/FNPT end connections
  • Compression – Uses compression ends that include a rubber seal and often a nut and anti-slip collar as well
  • Flange – Uses one flange end connection and either a threaded or slip connection for the other end

A reliable plumbing system starts with great materials and PVC or CPVC has been proven to offer those results.
