The advantages at a glance:
Completely leakproof (A)Because the same material is used throughout,the connection is as tight as a weld seam(helium leak rate ≤ 10-10 mbar l/s)
No dead space (B) andperfect pharmaceutical barrier (C)

Efficient, long-lasting and reliable:
ZeroCon Connection
ZeroCon is the simple and efficient solution if you want a new, built-to-last connection. It combines all theadvantages of a detachable connection with those of a welded connection. For this reason, ZeroCon canalso 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 oradapting the system at a later point. System maintenance and connection with further systems can be
carried out rapidly, easily and cost efficient.

The flexible solution for everyone who refuses tocompromise on safety: ZeroCon

Advantages of the ZeroCon connection

Microelectronics

LifeScience

New
EnergyUnique product design- Self-centering due to interlocking design- No risk of damage from excessive tightening torques- Easy, unproblematic connection with further pipelines- Easy to switch to other sizes- External forces and/or torques do not affect the connection- Turbulence-free- Quick and easy to install and remove- Clearly arranged, simplified product range (seal)- No impairment of flow
Sustainability and efficiency- Easy, rapid leak testing via test port
- Frequent reusability of flange and nut- Maintenance-free- Briefer flushing times
Extreme and high purity applications- Much more resistant to aggressive media than soft seals- Also suitable for high pressure systems up to 440 bar / screwed version (6381.66 psi)
- Temperature-stable from -196 °C (-320.8 °F) up to +350 °C (+662°F)- Also sterilizable with superheated steam- Use in ultra-high vacuum applications- 100% sterilizable, no deposits, films of bacteria or cultures- Meets the highest purity standards
Safety- As tight as a weld seam
- No contamination of the medium from the outside- No loss of media/leakage of toxic media to the environment- No outgassing of material that can contaminate the process medium- No cavities for medium to collect in- No detachment of coatings possible (no possibility of contamination of medium)45

ZeroCon and manifold systems
The perfect combination by Dockweiler
The use of prefabricated components is becoming more and more important in the installationof stainless steel piping systems. Modular construction increases efficiency, with connection components playing a key role.

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.

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).
