ZeroCon - Tight as a weld seam

The unique detachable connection with the tightness of a weld seam

Areas of Application

  • Semiconductor industry
  • Pharma & Biotechnology
  • Vacuum application
  • Fine chemical
  • Cryogenic application

ZeroCon is the new, patented, 100% stainless steel connection system for safe and rapid  connection of tube systems. 
With ZeroCon you make zero compromises!

ZeroCon is the simple and efficient solution if you want a new, built-to-last connection. It com-bines all the  advantages of a detachable connection with those of a welded connection. For this reason, ZeroCon can also be used in all areas of application and industries and is suitable for all applications. Try it for yourself and see.

The modular design of the ZeroCon connection means that there is nothing to stop you adding to or adapting the system at a later point. System maintenance and connection with further systems can be carried out rapidly, easily and cost efficient.

How ZeroCon works

Easy installation: self-centering, end stop and integrated leak test port

Hygienic design for maximum process purity

The seal ring adapts to fit perfectly when pressed in, ensuring complete sealing and no dead space.

  • Completely leakproof [A] as tight as a weld seam 
    (helium leak rate ≤ 10-10 mbar l/s)
  • No dead space [B]
  • Perfect pharmaceutical barrier [C]
ZeroCon Seal Function

Benefits:

Completely leakproof

Because the same material is used throughout, the connection is as tight as a weld seam (helium leak rate ≤ 10-10 mbar l/s)

Dynamic stress resistance

Anti-twist locking and outward precision fit prevent negative impact of external forces and torques 

Easy installation

Self-centering, end stop and integrated leak test port
 

Maintenance-free

No seal replacement required unlike with soft seals

Robust connection

Suitable for applications involving high-pressure, critical vacuum and extreme temperature conditions

The flexible solution for those who don't compromise on safety

ZeroCon and manifold systems

The use of prefabricated components is becoming more and more important in the installation  of stainless steel piping systems. Modular construction increases efficiency, with connection components playing a key role.

Reliable and safe

The ZeroCon connection was developed to combine the safety of conventional weld seams  with high ease of use. It provides a reliable and tight connection that can withstand demanding operating conditions.

Time and Cost Savings

The design of the ZeroCon allows for quick and easy assembly, reducing installation time and costs. This unique connection is available in two versions: a bolted version (1/4-1 inch) and a flanged  version (1-4 inch).
