ZeroCon®: the new generation of stainless steel connection

Schwer Fittings

ZeroCon® -Crown is made of solid high-purity stainless steel and serves as a safe and quick threaded connection of pipe networks, pipe joints and welded systems.

Features:

+ Absolutely leak-tight: Consistent material quality — Helium-leak-rate is ≤ 10-12 mbar

+ Zero dead spaces: Space between seal ring and joint: ≤ 10-25 μm

+ Perfect pharmaceutical barrier: No risk of bio-burdening; aseptic design

+ Robust connection: Suitable for application under high-pressure, critical vacuum and

extreme temperature conditions

+ Dynamic stress resistance: Interlocking geometry designed to prevent influence of external forces

and moments.

+ Temperature-stable, from -273°C to +450°C

+ Zero flow disturbances

+ Highest-grade surface finish: Ra ≤ 0,4 μm

+ Zero material outgassing: Stainless steel 1.4435 acc. to EN 10088-3

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

+ Zero maintenance: No preventive elastomer maintenance required

+ Full component traceability: Marking of all components

ZeroCon®-Crown shows absolute leak-tightness by helium leak test. Based on state-of-the-art measurement technology a leak rate of ≤ 10-12 mbar is measured.
