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 plain pipe connections and consist of 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 compression 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< Oyster 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.
Materials
The Wieland WICONNEC brand offers a range of copper materials in the form of rods and wires that are ideal for machined sockets and pins for plug connectors. This material portfolio also offers brass materials in addition to specially developed copper alloys for complex turned plug connectors.
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.
Wieland ecoline is our answer to enable your future business: the lead-free product line fulfills your individual needs for an efficient production and future oriented product development. And is, of course, compliant with the latest requirements of legislative directives on lead-free materials.

Wieland hot stamping rods
Good forging results can be obtained only when all links in the process chain have been matched to each other to the optimal effect. With Wieland hot stamping rods you are offered a forging stock which comprehensively fulfils these requirements. Your benefits: uniform dark surface for reproducible processing properties, tight diameter tolerances in the drawn size range, and hence precise configuration of the slug weight.
We can offer you a wide range of materials, geometries, and surface qualities to choose from. Many geometries are available from our sheets stores.

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.
