## Long description

SiGMA-Li TR4020 — 40×20 mm pipe fitting is a reducer tee designed to connect a 40 mm main line with a 20 mm branch in plumbing systems. The fitting creates a three-way junction that reduces pipe diameter at the branch while maintaining a straight-through 40 mm run. It is intended for water distribution and auxiliary pipework in domestic and light commercial installations where a controlled transition between pipe sizes is needed.
Advantages
The reducer tee provides a compact and reliable method to form a branch from a larger diameter supply line to a smaller branch line. Its configuration simplifies installation and minimizes the number of joints required for size transitions. The fitting is compatible with standard 40 mm and 20 mm pipe dimensions, offering predictable flow behaviour and straightforward integration into existing plumbing layouts.
Suitable for
 Domestic cold and hot water distribution
 Branching off main supply lines for fixtures and appliances
 Light commercial plumbing and service connections
 Retrofit work where downsizing from 40 mm to 20 mm is required
Key specifications
 Fitting type: reducer tee (three-way junction)
 Connection diameters: 40 mm main run, 20 mm branch
 Application: water distribution and auxiliary pipework
 Material: compatible with common plumbing materials (refer to product labeling for exact material)
 Typical installation environment: domestic and light commercial plumbing
How to use
Select the appropriate pipe ends and ensure they match the 40 mm and 20 mm connection sizes. Prepare pipe ends by cutting squarely, deburring, and cleaning to remove debris and grease. Insert the pipes into the corresponding ends of the reducer tee according to the manufacturer's recommended joining method (push-fit, solvent weld, or mechanical coupling as applicable). Confirm alignment and secure joints following standard plumbing practice and local codes. After installation, perform a pressure test of the system to verify there are no leaks at the new junction.
Usage recommendations
Use appropriate jointing techniques and compatible sealants or adhesives for the pipe material. Avoid applying excessive mechanical stress to the fitting during installation and ensure support for the main and branch pipes to prevent strain on the connection.
