Reducer tee VIEGA 42 x 22 x 42 mm soldered model 111595

Reducer tee VIEGA 42 x 22 x 42 mm soldered model 111595 is a copper fitting designed to create a durable three-way junction with a reduced branch. It is intended for soldered connections in copper piping systems and provides a watertight hydraulic link between two 42 mm runs and one 22 mm branch. The fitting is suitable for potable water and heating installations where a change of pipe diameter is required while maintaining a robust soldered joint.

Advantages

The reducer tee offers a stable, soldered connection that resists leaks and provides long-term reliability in copper piping systems. Its simple geometry enables straightforward installation with standard soldering techniques and ensures consistent internal flow characteristics between differing pipe diameters. Manufactured by VIEGA, the fitting is compatible with commonly used copper pipes and supports potable water and heating system requirements without the need for mechanical compression or threaded adapters.

Suitable for

• Potable water distribution in buildings where a diameter reduction is needed
• Heating systems and radiators requiring a branch at reduced size
• Domestic and commercial copper pipe installations using soldered joints
• Plumbing repairs or modifications where a permanent, soldered junction is preferred

When it may not be suitable

This soldered reducer tee is not suitable for plastic piping systems or installations that require push-fit or press-fit connections. It is also not appropriate where quick-disconnect or frequently reconfigurable connections are needed, since soldered joints are permanent and require heating to remove.

Key specifications

• Material: copper (soldered fitting)
• Connection type: designed for soldered joints
• Port sizes: two 42 mm ports and one 22 mm reduced port
• Application: potable water and heating installations

How to use

Prepare the copper pipes by cutting square, deburring and cleaning the pipe ends and the fitting surfaces. Apply appropriate flux to the joint area, insert the pipes fully into the fitting, and heat evenly with a suitable torch until the solder flows to form a continuous fillet around each joint. Allow the assembly to cool undisturbed and then verify the joint integrity by pressure testing according to local plumbing standards. Follow all safety procedures for soldering and local codes for potable water and heating system installations.

What to consider before purchase

• Ensure pipe outside diameters match the fitting sizes: 42 mm and 22 mm
• Confirm compatibility with soldered copper pipework and required system fluids (potable water or heating)**
• Verify local building codes allow soldered joints for the intended application
• Check that installation requires a permanent soldered connection rather than a mechanical or push-fit solution

Usage recommendations

Use appropriate flux and lead-free solder compatible with potable water systems, follow manufacturer guidelines for heating and cooling rates, and perform a pressure test after installation. If unsure about local regulations or soldering technique, consult a qualified plumber to ensure proper installation and compliance.
