ZeroCon: the latest generation of fittings

Schwer Fittings offers a real highlight with its own patented stainless steel fitting: The new generation of "tightness" due to material uniformity of seal and flange connection. With its many advantages, the ZeroCon fitting opens many cross-industry applications. All components are manufactured in our own Schwer Fittings plants on special machines.

Both thread connection and flange versions are available.

Advantages:

The fitting consists of a threaded connection, an insert, and a metallic sealing ring. It can be easily sterilized with superheated steam and is much more resistant to aggressive media than soft seals. It is temperature stable from -196° C to +300° C and insensitive to environmental influences (e.g. salt water, etc.).
For ultra-high-purity applications, all connectors, sealing rings and nuts are available electropolished and rinsed with ultrapure water if required, to meet the conditions of use in a clean room and with ultrapure media.
The ZeroCon fitting meets the highest purity standards and is made completely of stainless steel material 1.4435, with an internal surface roughness of Ra ≤ 0.4 μm. Nuts 3/4” and larger have a silver plated internal thread.
The surface treatment reduces friction in the tightening process and enables an accurate installation. The weld connections are prepared for orbital welding.
It offers no possibility of deposits or formation of cultures or a bacterial film, is 100% sterilizable and absolutely tight due to material uniformity.

The result of the bacterial test with an independent institute shows that ZeroCon® prevents the accumulation of any bacteria and the smallest organisms inside the pipe that comes into contact with the media. A perfect pharmaceutical barrier and therefore no germ accumulation due to the aseptic design
The helium leak test proves absolute tightness. With the current state of measurement technology, a leak rate of < 10 hoch -10 (mbar * l) / s to DIN EN 1779 Methode A3 is determined. Can also be used in hazardous areas.

The robust yet fine connection is suitable for applications under high pressure, critical vacuum or ultra-high vacuum and extreme temperature conditions. It is free of turbulence and does not interfere with the flow or contaminate the process medium with material outgassing. A simple and fast leak test is possible after installation.
The anti-twist protection by interlocking crown tips, prevents the action of external forces and torque. No possible loosening of the connection by torsional forces.
It is self-centering with installed end stop and integrated leak-test port.
Piggable due to a continuous bore.
The fitting is very easy to handle: quick, easy installation and disassembly without the risk of damage due to excessive tightening torques.
No maintenance work is necessary. Fittings are easily changed to alternative dimensions.
