Benefits of Using FlexAtex Connectors

FlexAtex connectors, incorporating Jacob™ pipe systems, meet stringent industrial demands, providing superior performance and reliability. Here are the detailed benefits of using FlexAtex connectors:


Compliance with Industry Standards

  1. FDA and ATEX Approved: Manufactured from transparent, FDA and ATEX-approved abrasion-resistant polyurethane. This ensures they meet stringent health, safety, and quality standards, making them suitable for various industrial applications, including food processing and explosive environments.


Superior Material Properties

  1. Abrasion Resistance: The polyurethane material offers excellent abrasion resistance, extending the connectors’ lifespan even in harsh conditions, wear and tear.
  2. Transparency: The polyurethane’s transparency allows for easy visual inspection of the system’s flow, facilitating maintenance and troubleshooting.


Versatile and Customisable

  1. Custom Lengths and Diameters: Manufactured in any length and diameter, ensuring a perfect fit for specific application requirements.
  2. Bespoke Shapes and Sizes: The flexibility to create bespoke shapes, sizes, and lengths allows for tailored solutions to unique industrial needs.


Easy Installation and Integration

  1. Quick Connect System: FlexAtex connectors easily fit with a standard Jacob™ Pull-Ring or Jacob Quick Connect Pull-Ring for quick release, eliminating the need for specialised tools and reducing installation time.
  2. Compatible with Existing Systems: They can be seamlessly incorporated into existing pipework systems, eliminating the need for on-site welding and making upgrades and maintenance more straightforward and less disruptive.


Enhanced Safety Features

  1. Alternative Clamps: For enhanced safety, alternative clamps are available to prevent accidental access, ensuring compliance with health and safety regulations.


Optimal Performance in Various Conditions

  1. Smooth Internal Surfaces: The smooth internal surfaces facilitate easy product flow and cleaning, ensuring efficient operation and maintaining hygiene standards.


Vibration Dampening

  1. Convoluted Gaiters and Bellows: These features can be incorporated into the connectors for vibratory sieve equipment or load cell weighing applications, effectively dampening vibrations.



  1. Low-Cost Mating Fixings: Jacob™ pipe welding end stubs and other mating fixings are readily available off-the-shelf at a low cost, making the overall system more economical.
  2. Minimal Maintenance: FlexAtex connectors require minimal maintenance due to their durable construction and resistance to environmental factors, reducing downtime and long-term costs.


Quick Turnaround and Custom Manufacturing

  1. Rapid Production: FlexAtex offers a quick turnaround on all designs, ensuring that custom connectors are produced and delivered promptly to meet urgent project timelines.
  2. In-House Manufacturing: The ability to manufacture in-house ensures high-quality control and the capacity to meet specific customer requirements efficiently.


Anti-Static Properties

  1. Dissipative Material: The anti-static polyurethane material used in FlexAtex connectors has been tested according to EN 60079-0:2017 clause 26:13, making it suitable for ATEX use. This property is crucial for applications in explosive atmospheres where static electricity must be controlled.


Application Versatility

  1. Wide Range of Applications: FlexAtex connectors suit various industrial sectors, including food and beverage, pharmaceuticals, chemical processing, and more, thanks to their versatile design and robust material properties.


Steel Rings and Flat Bar Options

  1. Pressure and Vacuum Applications: For applications requiring additional structural support under pressure and vacuum conditions, FlexAtex connectors can be fitted with steel rings and flat bars, enhancing their durability and performance.


FlexAtex – Specials Range

  1. Custom End Connections: If connecting from a Jacob ferrule at one end to another type of connection at the other, the FlexAtex – Specials range can accommodate these requirements, providing customised solutions for specific needs.


FlexAtex Product Range

Flex-MD: A metal-detectable polyurethane connector, ideal for environments where detecting foreign objects is critical.
