Reduction fitting PPSU 75-50 Uponor S-Press 1032885

Reduction fitting for Uponor S-Press systems

This PPSU 75-50 reduction fitting, designed for Uponor S-Press systems, allows connection of pipes with different diameters – 75 mm and 50 mm. It is a key element in installations where adaptation to existing infrastructure or connection of components with different specifications is required. Made of high-quality PPSU (polyphenylsulfone), it is characterized by durability and resistance to high temperatures and pressure.

Design and application

The fitting has a mounted steel clamping sleeve with an inspection hole, ensuring precise and secure connection. Thanks to the unique clamping execution indicator, it is easy to check if the connection has been made correctly. Diameter marking facilitates identification, and the leak test function allows verification of the installation's tightness. The optimized body shape improves the flow of medium in the installation.

The fitting is used in both drinking water installations (up to 70°C at 10 bar) and heating installations (up to 80°C at 10 bar). It is fully compatible with existing Uponor components, making it easier to modernize and expand installations. It can be used in residential and commercial buildings.

Advantages and benefits

• Durability and resistance: PPSU construction guarantees long-term operation even in difficult conditions.
• Safety: PZH approval and compliance with DVGW and AENOR standards confirm the safety of use, especially for drinking water.
• Fast installation: The S-Press system enables quick and reliable installation without the need for calibration and beveling of pipes.
• Easy identification: Color-coded diameter marking and clamping execution indicator facilitate the installer's work.
• Compatibility: Full compatibility with existing Uponor components minimizes costs and simplifies the installation process.
• High-quality materials: Lead-free material ensures safe and hygienic drinking water.
• Quality control: Leak test function allows for quick verification of connection correctness.
• Flow: Optimized body shape improves the flow of medium in the installation.

The fitting length is 115 mm, and the connection lengths are 69 mm and 47 mm, respectively, while the working lengths are 8 mm each for each connection. The maximum working pressure is 10 bar at a temperature of 20°C.
