Do you use primer on CPVC?
Primer: Primer is used to clean and soften the surface of the plastic to ensure a good solvent weld. It’s used with both PVC and CPVC, but is not required with ABS. The primer is a readily identified purple color.
Can PVC glue be used on CPVC?
To explain, you need to understand the difference between PVC and CPVC. PVC stands for polyvinyl chloride, while CPVC stands for chlorinated polyvinyl chloride. So, if all you have to bond two PVC pipes and fittings together is CPVC cement, it will work, but PVC cement cannot be used to bond CPVC pipes and fittings.
Should I use purple primer on CPVC?
Purple Primer can be used with all types, schedules and classes of PVC and CPVC pipe and fittings. A low VOC formulation. In most cases a successful solvent cement joint can be made without using a primer. Using Purple Primer is always recommended to make a good connection.
Can I use CPVC cement without primer?
What color is CPVC glue? The purple color is just a dye so that it’s easier to identify whether or not primer has been used on a particular joint. The yellow that you’re seeing is a one-step cement that, according to the manufacturer, can be used without a primer on CPVC.
Can I glue CPVC without primer?
What do you need to know about PVC primer?
The first step is pressing, and it is required to ensure contact between the two pieces being welded, maintain proper orientation of the pieces and to force intermolecular diffusion between the two pieces. The second step is getting the temperature of the material over its Tg by use of a cement.
Can You glue PVC pipe to CPVC pipe?
This means old-fashioned PVC cement will not be fully effective on CPVC. There is no special “CPVC to PVC glue,” so chemically joining CPVC and PVC requires solvent cement and primer that are strong enough to fully bond CPVC pipe. To connect PVC to a CPVC fitting (or vice versa) follow these steps:
Can a PVC pipe be welded without primer?
Take a PVC pipe and solvent weld it to a PVC tee on one end with primer. Then solvent weld it to another tee on the other end of the pipe without primer. This creates a pipe assembly with two solvent welded joints, one with primer application and one without. Refer to Figure 2 for a diagram.
How are PVC and CPVC used in different applications?
PVC and CPVC have different applications, so they are not typically used in the same types of applications. CPVC goes through an extra chlorination process, which lets it withstand high temperatures much more effectively than regular PVC.
