VIEGA soldered tee connector 42x28x42 mm model 110383 for copper pipe systems

VIEGA soldered tee connector 42x28x42 mm model 110383 is a copper fitting designed for creating reliable branch connections in copper pipe systems. The fitting is manufactured for capillary soldering and provides three-way connection geometry with two 42 mm ends and one 28 mm branch. It is intended for use in heating systems, potable water installations and general plumbing where soldered copper joints are specified. The product is supplied as a single soldered tee connector suitable for integration into existing copper piping networks.

Advantages

The VIEGA soldered tee connector offers a compact and robust design made of copper suitable for capillary soldering, ensuring leak-tight joints when installed correctly. Its standardized dimensions allow compatibility with common copper pipe sizes and fittings, while the three-way configuration simplifies branching and redistribution of fluids in a system. The smooth internal bore and consistent wall thickness support predictable flow characteristics and long-term mechanical stability.

Suitable for

• Branch connections in domestic and commercial heating systems
• Potable water distribution and plumbing networks
• Repairs and modifications in copper piping systems
• Applications requiring capillary (soldered) connections for durable joints

When it may not be suitable

This soldered tee is not suitable where press-fit, compression, or threaded connections are required, or in systems specified to use alternative materials such as plastic (PEX, PVC) or stainless steel without adapters. It should not be used in applications where soldering is prohibited due to safety or regulatory constraints, or where brazing or mechanical joint methods are mandated.

Key specifications

• Material: copper
• Connection type: capillary soldering (soldered joints)
• Dimensions: 42 x 28 x 42 mm (two 42 mm ends, one 28 mm branch)
• Configuration: tee (three-way) fitting
• Suitable media: potable water, heating fluids, general plumbing media
• Supply: single fitting (sold individually)

How to use

Prepare the copper pipes by cutting to length, deburring and cleaning the outer surfaces and the fitting sockets to remove oxides and contaminants. Apply appropriate flux to the joint areas, insert the pipes fully into the fitting sockets, and perform capillary soldering with a suitable solder alloy and heat source until solder flows uniformly around each joint. Allow joints to cool naturally and then inspect for continuous solder fillets and any visible gaps. After cooling, pressure test the assembled circuit according to applicable codes and standards before putting the system into service.

What to consider before purchase

• Confirm compatibility with the copper pipe diameters and wall thicknesses in your system
• Verify that capillary soldering is acceptable for the intended application and local regulations
• Ensure you have appropriate soldering tools, flux, and safety equipment for installation
• Check that the three-way tee configuration and branch size (28 mm) meet your hydraulic requirements

Usage recommendations

Use qualified personnel for soldering to ensure leak-tight joints and compliance with local plumbing and heating regulations. Perform a pressure test after installation and follow manufacturer or industry guidelines for compatible solder alloys and fluxes when working with copper fittings.
