VIEGA Viega 1126.1 Steel 45° Bend Elbow 28 mm, pack of 5

VIEGA Viega 1126.1 Steel 45° Bend Elbow 28 mm, pack of 5 is a compact steel pipe fitting designed to provide a reliable 45° change of direction in plumbing and heating pipework. Supplied as a set of five identical elbows, this component is intended for use with compatible Prestabo-style systems and metal piping where a press-fit, plug-in end solution is required. The fitting features a galvanised, non-alloyed steel body and an EPDM sealing element to ensure a tight connection under normal operating conditions.

Advantages

The elbow combines a non-alloyed galvanised steel construction with an EPDM sealing element, delivering corrosion-resistant mechanical strength and a durable seal for liquid systems. The plug-in end with press connection simplifies installation and reduces assembly time compared with threaded joints. Inclusion of the SC-Contur feature supports leak detection during commissioning and helps meet contemporary installation safety practices.

Suitable for (tasks / use cases)

• Changing pipe direction by 45° in domestic and commercial water supply lines
• Plumbing and heating installations using compatible Prestabo or press-fit metal piping systems
• Applications requiring compact fittings in confined spaces
• Replacement or extension work where a pack of identical elbows is needed

When it may not be suitable

This steel 45° elbow is intended for use with compatible press-fit pipe systems; it is not suitable for installations that require threaded, soldered, or welded connections. It is designed for metal piping systems and may not be appropriate for some plastic pipe materials unless an adapter or approved transition fitting is used. For applications with aggressive chemicals, extremely high temperatures, or special sanitary requirements, verify material compatibility and pressure/temperature ratings before use.

How to use

Prepare the pipe ends according to the press system manufacturer’s instructions, ensuring clean, deburred surfaces and correct insertion depth for the plug-in end. Position the Viega 1126.1 elbow onto the prepared pipe and perform the press operation with a compatible pressing tool and jaws suitable for 28 mm fittings. Confirm the press connection is fully formed and that the EPDM sealing element is correctly seated. After installation, carry out pressure and leak tests as required by local codes and the piping system’s documentation.

What to consider before purchase

• Confirm compatibility with your press-fit system and 28 mm pipe material
• Verify required pressure and temperature ratings for your installation
• Ensure you have the correct pressing tool and jaws for 28 mm fittings
• Check whether SC‑Contur compatibility or local commissioning procedures are required

Usage recommendations

Use the Viega 1126.1 elbow only with approved pressing tools and in accordance with the system manufacturer's installation instructions. Perform standard pressure tests after installation and follow local regulations for plumbing and heating system commissioning.
