VIEGA 45° Elbow 15 mm – Copper Fitting (model 345600)

VIEGA 45° Elbow 15 mm is a compact copper fitting designed to change the direction of 15 mm piping by 45 degrees in potable water and heating systems. Manufactured from copper for corrosion resistance and reliable mechanical performance, this elbow is suitable for residential and commercial plumbing, radiator connections and underfloor heating circuits. The fitting is compatible with standard 15 mm copper pipes and with systems that accept copper press or soldered joints, providing a stable joint for fluid transport.

Advantages

The 45° angle enables smoother directional changes compared with sharp 90° bends, reducing pressure loss and enabling tighter routing in confined spaces. Copper construction offers durable corrosion resistance, good thermal conductivity and long service life in domestic and commercial installations. Its compact 15 mm size allows straightforward integration into existing copper pipelines and heating circuits without bulky fittings.

Suitable for

• Potable water distribution in residential and commercial buildings
• Radiator and heating system connections
• Underfloor heating manifolds and branch runs
• Compact plumbing routes where gradual directional change is required

Key specifications

• Material: Copper
• Connection size: 15 mm
• Angle: 45 degrees
• Application: Cold and hot water, heating circuits
• Compatibility: Standard 15 mm copper piping and compatible joining methods

How to use

Prepare the pipe ends by cutting square and deburring to ensure full insertion and a leak-free joint. Depending on the installation method, join the elbow using the appropriate technique for copper fittings—soldering (capillary solder), press-fit tools if the fitting is designed for press connection, or other approved mechanical joining methods. Ensure pipes are aligned to the 45° orientation before completing the joint and allow any soldered joints to cool and be inspected for continuity and tightness prior to pressure testing the system.

Usage recommendations

Use appropriate pipe preparation tools and follow relevant plumbing codes and manufacturer guidance when installing copper fittings. Verify material compatibility with system fluids and operating temperatures, and perform pressure testing after installation to confirm joint integrity.
