Uponor S-Press PPSU fitting 40-40 1046401

Fittings for multilayer systems – an indispensable element of installation

The PPSU 40-40 Uponor S-Press compression fitting is a key element of plumbing and heating installations based on multilayer pipes. Made of high-quality polyphenylene sulfone (PPSU) with a stainless steel clamping sleeve, it provides a durable and leak-proof connection for pipes with a diameter of 40 mm. The fitting is designed to connect pipes of the same dimension, making it easier to build straight sections of the installation.

Design and application

The PPSU fitting is dedicated to use with the Uponor S-Press/S-Press PLUS system, guaranteeing compatibility and connection reliability. The use of PPSU ensures resistance to high temperatures and pressure, as well as chemical resistance, which translates into a long service life of the installation. The built-in leak test allows for verification of the connection correctness immediately after pressing, minimizing the risk of leaks. This is particularly important for installers who value speed and certainty of work.

Advantages and benefits

• Durability and reliability: PPSU material and stainless steel provide resistance to corrosion and mechanical damage, guaranteeing long-term use without the need for replacement.
• Fast installation: The Uponor S-Press pressing system significantly speeds up the installation process compared to traditional connection methods.
• Leak-proof: The built-in leak test confirms the correctness of the connection, eliminating the risk of leaks and energy losses.
• Chemical resistance: PPSU is resistant to the action of many chemical substances present in water and heating agents, which ensures the safety of the installation.
• Versatility: The fitting is compatible with Uponor Uni Pipe PLUS / MLC and Metallic Pipe PLUS multilayer pipes.
• Safety: Maximum working pressure of 10 bar ensures safe operation of the installation under typical operating conditions.
• Easy identification: The fitting design allows for easy identification of the diameter and verification of the correctness of the pressing.

Using PPSU fittings in central heating or plumbing installations guarantees peace of mind for both the installer and the end user – a solid connection is the basis for trouble-free operation of the system for years to come.
