How to Use Threaded PVC Fittings
Threaded PVC fittings allow you to connect PVC pipe to other types of plumbing, fixtures and appliances. Unlike other types of threaded plumbing fittings, threaded PVC fittings are easily damaged during installation. For this reason, you need to pay attention to the amount of pressure you use to tighten the fitting. If you overtighten it, the fitting may crack or the threads of the PVC fitting could strip from the fitting body. Does this Spark an idea?

Prepare the connection between the threaded PVC fitting and the PVC pipe. Apply PVC primer to the first 1-inch of one end of the exterior of the PVC pipe and then apply PVC primer to the inside of the slip-joint end of the threaded PVC fitting with the brush attached to the cap of the PVC primer. Allow the PVC primer to dry.

Connect the threaded PVC fitting to the PVC pipe. Apply the PVC glue to the primed area of the PVC pipe and the threaded PVC fitting with the brush attached to the cap of the PVC glue. Slide the threaded PVC fitting onto the PVC pipe before the PVC glue sets. Let the PVC glue joint cure before proceeding to ensure that the connection does not push apart.

Wipe the threads of the PVC fitting and apply thread sealant to the cleaned threads of the threaded PVC fitting and the thread of the fitting, appliance or plumbing fixture if you are installing a threaded PVC fitting that is larger than 1 inch in diameter.

Install the threaded PVC fitting. Hand-tighten the threaded PVC fitting into the final connection by turning the PVC pipe until the threaded PVC fitting no longer turns. Adjust the pipe wrench to fit onto the threaded PVC fitting and turn the threaded PVC fitting one or two turns with the pipe wrench. Do not overtighten the threaded PVC fitting.
