Copper 90° Elbow VIEGA ŁUK CU 1K 42 (MPN 108052) — copper pipe fitting 42 mm

VIEGA ŁUK CU 1K 42 is a 90° copper elbow designed for creating reliable directional changes in copper piping systems. With a nominal diameter of 42 mm, this fitting is intended for plumbing and heating applications where a compact, durable elbow is required to join two segments of copper pipe. The single-piece construction provides a smooth internal flow path and maintains the thermal and corrosion-resistant properties of copper in potable water and heating installations.

Advantages

The copper 90° elbow offers good thermal conductivity and long-term corrosion resistance typical of copper materials. Its compact 90° bend minimizes space requirements while ensuring a stable mechanical joint when installed by soldering or brazing according to standard practice. The single-component form provides consistent dimensions and predictable flow characteristics for hydraulic calculations and installation planning.

Suitable for

• Residential hot and cold water distribution
• Heating systems and radiator connections
• Commercial plumbing installations requiring copper pipework
• Gas lines where copper fittings are permitted by local codes

Key specifications

• Material: copper
• Angle: 90° elbow
• Nominal pipe diameter: 42 mm
• Connection type: designed for soldering or brazing to copper pipe
• Application: potable water, heating circuits, compatible with gas where allowed

How to use

Prepare the copper pipes by cutting to length and deburring the ends, ensuring a clean, oxide-free surface for soldering or brazing. Fit the elbow onto the pipe ends to confirm correct alignment and clearance. Apply appropriate flux to the joint, heat evenly with a suitable torch until the flux activates and solder or brazing filler flows into the joint to form a continuous seal. Allow the joint to cool naturally and inspect for full capillary penetration and a smooth external fillet. Follow local codes and manufacturer guidelines for pressures, temperatures, and approved joining methods.

Usage recommendations

If used in potable water or heating systems, ensure compatibility with system operating pressures and temperatures. Use lead-free solders and approved fluxes for drinking water installations. Verify local regulations for use of copper fittings in gas applications before installation.
