The type of PVC pipe seals that you need will depend on the specific application. For example, if you are sealing a joint between two pipes, you will need a rubber gasket or O-ring. If you are sealing a valve, you will need a thread sealant. And if you are joining two pipes together, you will need a bonding cement.

When choosing a PVC pipe seal, it is important to consider the following factors:

• The type of pipe and fitting that you are sealing
• The pressure and temperature of the fluid that will be flowing through the pipe
• The environmental conditions that the seal will be exposed to
• The cost of the seal

It is also important to follow the manufacturer’s instructions when installing the seal. This will help to ensure that the seal is properly installed and that it will provide a leak-free seal.
