There are several options for sealants for threaded PVC joints, depending on the specific application and the materials involved. Here are a few common choices:

  1. Teflon tape: This is a thin, white tape made of PTFE (polytetrafluoroethylene) that is wrapped around the threads of the joint to create a tight seal. It is inexpensive, easy to apply, and effective for most low-pressure applications.
  2. Pipe dope: This is a paste-like substance that is applied to the threads of the joint. It is typically made of a mixture of lubricants, fillers, and sometimes a resin or solvent. It provides a more permanent seal than Teflon tape and can be used for higher-pressure applications.
  3. PVC cement: This is a type of glue that is used to bond PVC pipes and fittings together. It can also be used to seal threaded joints, although it is not as common as Teflon tape or pipe dope for this purpose. PVC cement should be used only on PVC parts, not on other types of plastic or metal.

When using any sealant for threaded PVC joints, it is important to follow the manufacturer’s instructions carefully and to use the appropriate type of sealant for the application. Additionally, it’s a good practice to check the joint periodically for leaks and reapply sealant if necessary.
