Pipe fittings are necessary to join together pipes, or to change the direction of an existing pipe. Pipes and pipe fittings are made of a variety of materials, depending on the fluid or gas being transported. Most pipe fittings tend to be either threaded or able to slip over the pipes they connect. Whether you are using steel pipes of PVC pipes, a chemical solvent is required to create a seal between the pipe and the fittings.

Things You'll Need

  • Pipe
  • Pipe fittings

Measure the required length of the pipe to be installed, keeping in mind the extra length required where the pipe will be inserted into the fitting. Mark this length on the pipe.

Cut the pipe to the desired length with a hacksaw. If it is a metal pipe, it will be easier to use a reciprocating saw or a grinder. Smooth the cut ends of the pipe with a utility knife if the pipe is made out of plastic, or with a grinder if it is metal.

Insert the pipe into the fittings as a dry fit to confirm that it is the correct size. Remove the pipe from the fittings.

Apply a chemical cement that is appropriate for the type of piping material. Spread it on the inside of the fitting and the outside of the pipe.

Slide the pipe into the fitting until it is fully inserted. Twist it a quarter turn to spread the cement and ensure it is snugly fitted.

Hold onto the pipe and fitting for 60 seconds to ensure the cement dries. Wipe away the excess cement with a damp rag.

Tips & Warnings

  • Wear gloves to avoid getting the chemical cement onto your skin.
