Solder fitting
For connoisseurs of the plumbing and heating trade, the Conex | Bänninger >B< is a trademark that has stood for safety, quality and innovative products since 1909.

Fittings made of copper from Conex | Bänniger of the 5000 series: this material is oxygen-free and contains a copper mass fraction of at least 99.90%. It has excellent soft and hard solderability.

Gunmetal fittings from Conex | Bänniger of the 4000 and 3000 series: the gunmetal alloy of the cast fittings fully complies with the requirements of the new EN 1982 and can therefore be used for drinking water in accordance with ÖNORM
B 5014-3. The alloy offers the highest possible protection and has good soft and hard solderability.

CONEX clamping ring connectors
CONEX clamping ring connectors belong to the group of metal-sealing smooth pipe connections and consist of a fitting body, clamping ring and union nut. The tubes to be connected are pushed through the pre-assembled connection into the fitting body as far as it will go and the union nut is tightened by hand. The union nuts are tightened with commercially available tools or with the CONEX wrench. In the process, the clamping ring deforms and forms the metallic sealing connection between the tube and the fitting.

>B< Press Fitting and >B< Press Gas Fitting
With the current >B< Press connection technology made of material copper and gunmetal, we offer another highly economical installation technology. >B< Press Fittings series P4000 and P5000 have been specially developed for the field of plumbing and heating installation and can also be used for many other applications. The >B< Press Fittings range includes over 300 different items in copper and gunmetal materials. The >B< Press Gas Fittings series PG4000 and PG5000 have the quality mark certificate no. G 2.692 for gas.

>B< Oyster
The high quality transition coupling >B< Oyster made of gunmetal allows a quick, clean and economical assembly of all screwed components with internal thread. Application in the fields of drinking water, rainwater, heating, oil-free compressed air and in industry. The cold and energy-independent connection technology is particularly suitable for installation in areas at risk of fire. >B<-Oysters are detachable and reusable.

Wieland manufactures solid and hollow copper sections in a wide range of sizes. Featuring contours close to the final geometry, these sections help you obtain your finished parts in just a few operations. Together with you, we develop complex sections of copper from the draft to the initial prototypes to series production.

Wieland recognized the potential of environmentally friendly, lead-free machining brass at a very early date, and adopted the pioneering role in Europe by developing ECOBRASS. This proved to be a farsighted course into the future. Today, ECOBRASS is marketed worldwide over a cooperation network and available, even in smaller quantities, from trade partners. We also market this material under the name “CUPHIN” for sanitary products.

Drinking water is our most important food. The quality of drinking water must be of such a high standard that it can be enjoyed without restriction throughout life. For this reason, ever stricter requirements are being imposed worldwide on materials that come into contact with drinking water. The appropriate selection of materials and products for drinking water installations is therefore extremely important. Technical, economic, but especially hygienic and health aspects play a major role.
Copper alloys have proven themselves technically and hygienically billions of times worldwide in drinking water installations and will therefore continue to be the basis for clean drinking water in the future.

K65 - Sustainable and efficient

Sustainable and efficient – two keywords that have had a decisive impact on our time and have gained in relevance in recent years, especially in refrigeration. Increased environmental awareness in society and industry has therefore led to a kind of renaissance of natural refrigerants, especially CO₂. Wieland supports this turnaround with a tube system that meets the high requirements of CO₂ as a refrigerant.

Wieland K65 tubes have been designed for CO₂ applications in the commercial field, especially that of supermarket refrigeration systems. Wieland K65 alloy provides the mechanical strength high enough to withstand the high operating pressures of CO₂. At the same time, K65 tubes have outstanding processing properties, similar to those of standard copper (Cu-DHP/C12200).

All Wieland K65 tubes are available in the soft condition (R300/O61) to ensure excellent bending / flaring and collaring properties.

Wieland K65 tubes are offered from stock in two pressure ranges, 80 bar and 120 bar, and in dimensions ranging from 3/8” up to 2-1/8”.

Moreover, K65 tubes are also available in individual dimensions and different delivery forms.
For industrial processing, in particular CO₂ heat exchanger (evaporator / gas cooler) manufacturing, level wound coils (LWC) are offered.

K65 - Sustainable and efficient

two keywords that have had a decisive impact on our time and have gained in relevance in recent years, especially in refrigeration. Increased environmental awareness in society and industry has therefore led to a kind of renaissance of natural refrigerants, especially CO₂. Wieland supports this turnaround with a tube system that meets the high requirements of CO₂as a refrigerant.

Wieland K65 tubes have been designed for CO₂applications in the commercial field, especially that of supermarket refrigeration systems. Wieland K65 alloy provides the mechanical strength high enough to withstand the high operating pressures of CO₂. At the same time, K65 tubes have outstanding processing properties, similar to those of standard copper (Cu-DHP/C12200).

Innergrooved K65 tubes for manufacturing of CO₂heat exchangers (evaporator / gas cooler) are available in individual dimensions. These are delivered in level wound coils (LWC) or straight lengths alternatively.

Wieland K65 tubes are also available from stock in standard dimensions.
