## Long description

Uponor S-Press reducing tee 25-16-20 DWZ is a press-fit fitting for PEX plumbing systems, designed to create a reduced branch connection between 25 mm, 16 mm and 20 mm pipes. Intended for potable water and heating installations, the fitting enables fast assembly with a secure press joint that eliminates the need for soldering. The compact geometry and DWZ finish support installation in distribution manifolds, risers and compact service shafts where space and reliability are important.
Advantages
The fitting offers a reliable leak-resistant press connection when installed with compatible press tools and jaws. Its reducing tee geometry allows transition from a larger supply line to smaller branch lines without additional adapters. Made for use with PEX piping, the S-Press tee simplifies installation by reducing assembly time and providing consistent joint quality. The design minimizes the need for thermal joining methods and reduces on-site labour associated with soldering.

How to use
Prepare pipe ends by cutting square and deburring, then insert pipes fully into the fitting until the defined stop.
