Compression tee VIEGA solder connection 42x35x42 mm 113711

The VIEGA solder connection compression tee 42x35x42 mm is a compact plumbing fitting designed to create a branch from a 42 mm main run to a 35 mm branch using soldered copper pipe joints. Intended for water and heating installations, this tee enables a reliable, permanently sealed connection when installed by a qualified fitter. The fitting is made to VIEGA manufacturing standards for dimensional accuracy and compatibility with common copper and compatible metallic piping used in residential and commercial systems.

Advantages

The tee provides a durable soldered joint that resists leaks and thermal stress when installed correctly. Its compact geometry allows installation in confined spaces and simplifies routing by offering a perpendicular branch from the main line. The design supports conventional soldering methods, giving installers a straightforward joining procedure without the need for additional mechanical fittings.

Suitable for

• Domestic and commercial water supply pipelines
• Heating system pipework and radiator connections
• Repair and retrofit works where a 35 mm branch is required from a 42 mm main line
• New build plumbing installations using copper or compatible metallic pipes

Key specifications

• Main run outside diameter: 42 mm
• Branch outside diameter: 35 mm
• Connection type: soldered/capillary joint
• Material compatibility: copper and compatible metallic piping
• Orientation: T-branch (perpendicular branch off main run)

How to use

Prepare the pipe ends by cutting square, removing burrs, and cleaning the surfaces to be joined. Apply appropriate flux to the fitting and pipe ends, assemble the tee onto the pipes, and perform soldering with a suitable heat source following applicable codes and safety practices. Allow the joints to cool naturally and inspect for continuous capillary solder flow around each joint. Pressure test the system after installation and cooling to verify leak-tight performance.

Usage recommendations

Use qualified installers and follow local plumbing regulations. Match the fitting to pipe wall thickness and material. Use flux and solder alloys recommended for potable water or heating systems as required, and ensure adequate ventilation and heat protection for surrounding materials during soldering.
