Polyurethane FDA & ATEX Bellows

At Flexible Connections Ltd, we specialise in designing and manufacturing bespoke polyurethane FDA and ATEX bellows to meet our customers’ specific requirements. 


FDA-Approved and ATEX-Rated

Our polyurethane (PU) materials are FDA-approved for food-grade applications, making them ideal for industries where hygiene and safety are paramount. Additionally, our PU bellows can be ATEX-rated, which means they are suitable for use in hazardous explosive environments. This dual compliance ensures that our products meet stringent safety and quality standards, providing peace of mind for our clients across various sectors.


Exceptional Abrasion Resistance and Transparent

One key benefit of using polyurethane in our flexible connections is its excellent abrasion resistance. This property makes our bellows highly durable and capable of withstanding harsh operating conditions. Furthermore, the transparency of polyurethane allows for easy visual monitoring of product flow, which is crucial in many applications to ensure smooth and efficient operation.


Customisable to Your Specifications

We understand that each application is unique, so we offer bespoke bellows tailored to your requirements. Our standard design features a single central convolution that allows for axial compression. However, we can add convolutions to accommodate more significant movement or vibration. This customisation ensures that our flexible PU connectors can handle axial and lateral movements, making them suitable for high-vibration and sieve applications.


Additional Features and Design Options

In addition to the basic design, we offer a range of additional features to enhance the functionality of our flexible connections. These include:

  • Flanges: We can integrate flanges into the design to facilitate easy installation and secure attachment to your existing systems.
  • Conical Reducers: We can design bellows with conical reducers for applications requiring a transition between different pipe sizes to ensure a smooth flow.
  • Internal PU Flow Sleeves: These sleeves help guide the product and prevent the formation of lips where product buildup can occur. This feature is particularly beneficial in maintaining cleanliness and efficiency in your operations.


Standard Polyurethane Flexible Connectors

We recommend our standard polyurethane flexible connectors for applications where movement or misalignment is not a primary concern. These connectors provide a reliable performance in a variety of settings. You can find more information about our standard flexible PU connectors here.


Anti-Static Polyurethane for ATEX Applications

Safety is a top priority at Flexible Connections Ltd. Our anti-static polyurethane material is suitable for ATEX use. This property is crucial in preventing static electricity buildup, which can be a significant hazard in explosive environments. We advise seeking independent expert advice to ensure the suitability of our material for your specific application, as safety standards can vary depending on the environment and operational conditions.


Applications of Custom Polyurethane Bellows

Our custom polyurethane bellows are used across various industries, each with unique requirements and challenges. Some of the standard applications include:

  • Food and Beverage Industry: Our PU bellows’ FDA-approved nature makes them ideal for food processing and packaging systems. Their transparency and easy-to-clean properties ensure that hygiene standards are maintained.
  • Pharmaceutical Industry: In environments where cleanliness and contamination control are critical, our bespoke bellows provide a reliable solution for handling sensitive materials.
  • Chemical Industry: Polyurethane’s durability and chemical resistance make our bellows suitable for handling corrosive substances and ensuring safe operation.
  • Manufacturing and Processing Plants: Our flexible PU connectors offer the flexibility and resilience needed to maintain system integrity in high-vibration and movement applications.
