• Rubber O-rings: These are the most common type of PVC pipe seals. They are made of a soft, flexible rubber that is compressed between the two pipes. O-rings are available in a variety of sizes and materials to fit different pipe diameters and applications.
• Gaskets: Gaskets are made of a variety of materials, including rubber, plastic, and elastomers. They are typically thicker than O-rings and are used in applications where a higher degree of sealing is required.
• Spigot gaskets: Spigot gaskets are a type of gasket that is specifically designed for PVC pipes. They have a groove that fits over the spigot end of the pipe. Spigot gaskets for PVC pipe
• Bell gaskets: Bell gaskets are a type of gasket that is specifically designed for PVC pipes. They have a flange that fits into the bell end of the pipe Bell gaskets for PVC pipe
• Urethane seals: Urethane seals are a type of seal that is made of a durable, synthetic rubber. They are resistant to chemicals and can withstand high pressure and temperature. Urethane seals for PVC pipe

The type of PVC pipe seal that you need will depend on the specific application. For example, if you are sealing a small, low-pressure pipe, an O-ring may be sufficient. However, if you are sealing a large, high-pressure pipe, you may need to use a gasket or urethane seal.

When choosing a PVC pipe seal, it is important to consider the following factors:

• The type of pipe: The type of pipe will determine the type of seal that is needed. For example, O-rings are typically used for smaller pipes, while gaskets are typically used for larger pipes.
• The pressure rating: The pressure rating of the seal must be higher than the pressure of the fluid that will be flowing through the pipe.
• The temperature rating: The temperature rating of the seal must be compatible with the temperature of the fluid that will be flowing through the pipe.
• The material compatibility: The seal must be compatible with the material of the pipe.
• The cost: The cost of the seal will vary depending on the type, size, and material.

It is important to choose the right PVC pipe seal for the application. By considering the factors above, you can ensure that you choose a seal that will provide a long and reliable service.
