Types of 2″ PVC Conduit
Non-Metallic PVC Conduit
Non-metallic PVC conduit is widely used for electrical applications. It is lightweight and easy to handle, which makes it a popular choice for both DIY projects and professional installations. Available in Schedule 40 and Schedule 80, this type of conduit can be used in various environments, including residential and commercial settings.
Rigid PVC Conduit
Rigid PVC conduit is designed for more demanding applications. It offers higher resistance to physical damage and is suitable for commercial and industrial environments. Its robust design ensures that it can withstand harsh conditions, making it ideal for outdoor installations.
Gray PVC Conduit
The gray PVC conduit is specifically designed to resist UV rays, making it suitable for outdoor applications. Its non-corrosive nature allows it to maintain structural integrity over time, even when exposed to the elements.
Bell End PVC Conduit
Bell end PVC conduit features a flared end that allows for easy connections to other conduits or fittings. This convenience saves time during installation and helps achieve a more secure fit, reducing the risk of damage over time.
Applications of 2″ PVC Conduit
Electrical Wiring
The primary use of 2″ PVC conduit is to protect electrical wiring. It is commonly used in both residential and commercial applications. The conduit shields wires from moisture, chemicals, and physical damage.
Plumbing
In addition to electrical applications, 2″ PVC conduit can also be used in plumbing. Its resistance to corrosion and chemicals makes it suitable for various fluid transport applications.
Outdoor Installations
Due to its durability and UV resistance, gray PVC conduit is perfect for outdoor installations where exposure to sunlight and moisture is a concern. This conduit can protect wiring in outdoor lighting and irrigation systems.
Industrial Applications
Rigid PVC conduit is often used in industrial settings where there is a high risk of physical damage. Its strength and durability make it ideal for environments like factories and warehouses.

Installation Tips for 2″ PVC Conduit
Tools Required
Before starting the installation, ensure you have the following tools: a PVC cutter, measuring tape, level, and solvent cement. These tools will facilitate a smooth installation process.
Cutting and Joining
When cutting the conduit, ensure the cuts are straight for a secure fit. Use solvent cement to join sections together, following the manufacturer’s instructions for the best results.
Bending and Supports
For any bends in the conduit, use a heat gun to soften the PVC before bending. Ensure to support the conduit every 10 feet to comply with electrical codes and prevent sagging.
Safety Precautions
Always wear safety goggles and gloves when working with PVC conduit to protect against accidental cuts and chemical exposure from solvent cement.
