Copper elbow 90° 18 mm VIEGA model 100148 for plumbing and heating installations

VIEGA Copper elbow 90° 18 mm (model 100148) is a solderless copper fitting designed for plumbing and heating installations. The 90-degree bend provides a compact directional change for 18 mm copper tubing in potable water systems, heating circuits and general pipe routing. Manufactured from copper, this elbow delivers corrosion resistance and stable mechanical properties suitable for residential and light commercial applications where reliable joint integrity is required.

Advantages

The copper 90° elbow features a clean internal bore and consistent wall thickness to support efficient water flow and reduce turbulence at the bend. Its material properties provide good thermal conductivity for heating systems and long-term resistance to corrosion in potable water installations. The fitting’s dimensions match standard 18 mm copper tubing, enabling straightforward installation and compatibility with common joining methods used in plumbing and heating work.

Suitable for

• Directional changes in 18 mm copper water supply lines
• Connections within residential and commercial heating circuits
• Routing potable water in kitchens, bathrooms and utility rooms
• General pipe layout where 90° turns are required

Key specifications

• Material: copper
• Angle: 90 degrees
• Nominal tube size: 18 mm
• Application: potable water and heating systems
• Connection type: push-fit or solder-compatible (depending on system requirements)
• Operating temperature: suitable for typical domestic hot water and heating temperatures

How to use

Prepare the 18 mm copper pipe by cutting squarely and deburring the cut end to ensure a smooth mating surface. Insert the pipe into the elbow until it seats fully according to the chosen joining method. For soldered joints, clean and flux the surfaces before applying heat and solder; for press or push-fit systems follow the manufacturer’s instructions for engagement depth and tool use. Verify alignment and support the pipe to prevent strain on the elbow once the joint is completed.

Usage recommendations

Use appropriate jointing techniques compatible with copper fittings and the specific installation system. Ensure system pressure and temperature ratings are within the limits of copper tubing and associated fittings, and provide adequate mechanical support and thermal expansion allowances in heating circuits.
