Uponor S-Press PPSU reducing coupling 40-25 1039941

Uponor S-Press reduction fitting

This PPSU reduction fitting, designed for Uponor S-Press systems, allows connection of pipes with different diameters – in this case 40 mm and 25 mm. It is a key element when changing the diameter of the installation, ensuring a tight and reliable connection. Made of high-quality PPSU plastic, it is characterized by resistance to high temperatures and pressure.

The fitting has a steel clamping sleeve with an inspection hole, which facilitates control of the connection correctness. Additionally, a unique clamping execution indicator and a leak test indicator allow for quick and certain identification of the connection status. The body shape has been optimized for flow, minimizing hydraulic resistance.

Application and properties:

• Diameter reduction: Allows a smooth transition between pipes with a diameter of 40 mm and 25 mm in water and heating installations.

• Compatibility: Fully compatible with existing Uponor S-Press system components – it can be easily integrated with previously made installations.

• Durability and resistance: Made of PPSU provides high resistance to corrosion, high temperatures (up to 95°C for a short time) and working pressure up to 10 bar.

• Easy identification: Clear diameter markings and connection control indicators make it easier for the installer to work and allow for quick verification of correct assembly.

• Safety: It has PZH approvals, a National Declaration of Performance and a DVGW and AENOR certificate, confirming compliance with applicable safety standards and regulations.

The fitting is ideal for both drinking water installations (operating temperature 0-70°C) and heating (operating temperature up to 80°C). Thanks to the three-stage installation and innovative access to product data via a QR code, installation is quick, simple and intuitive. GW and GZ threads comply with EN 10226-1 standard. The length of the fitting is 80 mm, and the connection lengths are 45 mm and 34 mm with a working connection length of 6mm each.
