Types of Rubber Expansion Joint Liners

When it comes to choosing the right rubber expansion joints for your home or business, there are many options. EPDM, TFE, FEP, and PTFE liners are a few of the options available. However, these liners may not be suitable for all projects. The following information will provide an overview of the differences between these types of liners.

PTFE liners

Rubber expansion joints can be made more reliable with PTFE liners. These liners are able to withstand high temperatures and high pressures, making them a good choice for hot and dirty environments. There are several types of PTFE liners available for use in rubber expansion joints. They come in different shapes, materials, and sizes.


EPDM Rubber expansion joints are designed to absorb movement and prevent pipework and ductwork from buckling and pulling apart. They also protect your piping system from leaks and other damages. The EPDM expansion joints can be customized according to your specifications, depending on the use and the environment.


TFE rubber expansion joints can be used for a variety of purposes and applications. They are made from synthetic or natural rubber and have a protective lining. They are designed with a sphere shape to distribute forces evenly over a large area. Other features of these types of expansion joints include wire-reinforced flanged collars and embedded nylon cord reinforcement. They are available in several different styles and materials and are easy to install.


If you’re considering using FEP rubber expansion joints, consider the following. ThisĀ see here now versatile material is available in a variety of configurations, sizes, and shapes. They’re able to withstand temperatures up to 400 degrees Fahrenheit without delamination. They can also be manufactured in custom sizes and shapes.


The Metraloops rubber expansion joints are manufactured by Metraflex. These elastomeric pipes are used in a variety of applications, including fire sprinkler systems. They also can be used for vibration isolation in piping systems. Additionally, Metraflex offers a range of specialty piping products. Their engineering staff can assist with specific applications. They also produce ceiling hangers, strainers, Y-type strainers, suction diffusers, and more.

Style 301 single sphere connectors

Style 301 single sphere rubber expansion joints feature a high-quality EPDM rubber tube and cover, and a nylon tire cord for reinforcement. They are available with special elastomers, such as Nitrile or Butyl, if desired. The EPDM material provides superior physical and temperature properties. These expansion joints also feature galvanized steel floating flanges that engage the rubber beaded end of the expansion joint. This allows for ease of installation.
