Reduction fitting PPSU 63-50 Uponor S-Press 1032884

Pipe diameter reduction for Uponor S-Press installations

The Uponor S-Press PPSU 63-50 reducing coupling is a key element enabling the connection of pipes with different diameters in water and heating installation systems. Made of high-quality PPSU plastic, it ensures durable and reliable connections, and its design is optimized for minimal flow resistance. This coupling is indispensable when adapting existing installations or designing new ones where adaptation to various system components is required.

Solid construction and easy installation

The coupling is characterized by precise workmanship and a mounted steel clamping sleeve with an inspection hole, which facilitates quality control of the connection. The unique clamping execution indicator and leak test function further increase confidence in proper installation. This means that both professional installers and end-users can rest assured about the safety and tightness of the installation. Compatibility with existing Uponor S-Press components guarantees seamless integration with existing systems.

Operating parameters and compliance with standards

The PPSU 63-50 reducing coupling is designed for use with drinking water and in heating systems. For drinking water, the constant operating temperature is from 0°C to 70°C with a maximum working pressure of 10 bar, and the maximum short-term temperature is 95°C. In heating systems, the permissible constant operating temperature is 80°C at a pressure of 10 bar, while the maximum short-term temperature is 100°C. The product has PZH approvals, a National Declaration of Performance and a DVGW certificate, which confirms its compliance with applicable standards and safety of use. GW and GZ threads meet the requirements of EN 10226-1.

Key product features:

• Diameter reduction: allows connection of pipes with diameters of 63 mm and 50 mm.
• PPSU material: provides high mechanical strength and corrosion resistance.
• Clamping execution indicator: facilitates quality control of the connection.
• Leak test function: allows for quick checking of installation tightness.
• Compatibility: fully compatible with the Uponor S-Press system.
• Approvals and certificates: confirm safety and compliance with standards (PZH, National Declaration of Performance, DVGW).
• Length: The total length of the coupling is 115 mm, and the lengths of the individual working parts are 69 mm and 47 mm respectively (the working length of the connection is 8mm for each side).
• Maximum working pressure: up to 10 bar at 20°C.

Using this coupling allows for flexible installation design and minimizes the risk of problems related to differences in pipe diameters – saving time and costs associated with potential repairs.
