Proper Techniques for Joining PVC Conduit Together

PVC conduit is a popular choice for protecting electrical wiring in both residential and commercial settings. When installing PVC conduit, it is important to ensure that the pieces are joined together properly to create a secure and watertight seal. In this article, we will discuss the proper techniques for joining PVC conduit together to ensure a successful installation.

One of the most common methods for joining PVC conduit together is using PVC solvent cement. This type of cement is specifically designed for use with PVC pipe and fittings and creates a strong bond between the pieces. To use PVC solvent cement, start by cleaning the ends of the conduit and fittings with a PVC primer to remove any dirt, grease, or debris. Next, apply a generous amount of solvent cement to both the conduit and fitting, making sure to cover the entire surface area. Finally, quickly push the pieces together and hold them in place for a few seconds to allow the cement to set.

Another method for joining PVC conduit together is using PVC compression fittings. These fittings are designed to create a tight seal between the conduit pieces without the need for cement. To use PVC compression fittings, simply slide the fitting onto the conduit and tighten the compression nut to secure the pieces together. This method is quick and easy to use, making it a popular choice for DIYers and professionals alike.

For installations where flexibility is required, such as in outdoor applications or areas with high vibration, PVC expansion fittings are a great option. These fittings allow the conduit to expand and contract with temperature changes without compromising the seal between the pieces. To use PVC expansion fittings, simply slide the fitting onto the conduit and tighten the compression nut to create a secure connection.

In some cases, it may be necessary to join PVC conduit together using a PVC coupling. Couplings are used to connect two pieces of conduit that are not able to be joined directly. To use a PVC coupling, simply slide the coupling onto one end of the conduit and then slide the other end of the conduit into the opposite side of the coupling. Tighten the coupling screws to create a secure connection between the pieces.

When joining PVC conduit together, it is important to ensure that the pieces are aligned properly to create a straight and secure connection. Use a level or straight edge to check that the conduit pieces are lined up correctly before securing them together. This will help to prevent any leaks or gaps in the connection that could compromise the integrity of the installation.

In conclusion, there are several methods for joining PVC conduit together, each with its own advantages and considerations. Whether using PVC solvent cement, compression fittings, expansion fittings, or couplings, it is important to follow the manufacturer’s instructions and best practices to ensure a successful installation. By taking the time to properly join PVC conduit together, you can create a secure and watertight seal that will protect your electrical wiring for years to come.
