Reducing tee PPSU 25-32-25 Uponor Q&E 1008712

Material and construction

The reducing tee is made of polyphenylsulfone (PPSU) - a thermoplastic material with high thermal and mechanical resistance. Unlike brass counterparts, PPSU is not subject to corrosion or dezincification, which translates to the durability of connections over long-term use.

The use of this material allows operation in water supply and radiator installations at a pressure of up to 10 bar at a temperature of up to 95°C (at lower pressures). The design includes three nipples with a clamping ring - two with a diameter of 25 mm and one central 32 mm - enabling a smooth transition between pipe sizes in a single component.

Q&E connection technology

The Uponor Q&E (Quick & Easy) system is based on the ring shrinkage principle. The installation process is as follows:

1. The end of the PE-Xa pipe is expanded using a dedicated expansion tool.
2. The tee is inserted to the appropriate depth.
3. The Uponor Q&E ring is placed (available separately - white for 32 mm diameter).
4. The ring automatically shrinks during cooling, pressing the pipe against the fitting with uniform pressure.

This method eliminates the need for welding, threading, or using adhesives - the connection is created in a few seconds and is completely leak-proof. The absence of metal elements in the connection itself eliminates the risk of galvanic corrosion when connecting with other materials.

Application and compatibility

The 25-32-25 reducing tee is primarily used where the installation requires a change in pipe diameter while maintaining a tee branching - typical situations include:

• Heating circuit distribution - transition from a 32 mm main pipe to two 25 mm supply lines.
• Water installations - expansion of a riser or level while maintaining flow continuity.
• Connections with manifolds - adapting smaller diameters to smaller circuits.

The component works with the entire range of Uponor PE-Xa pipes produced using the Engel method (PN-EN ISO 15875 standard), available in S3.2 and S5.0 series as well as eval PE-Xa pipes with an EVOH oxygen barrier compliant with DIN 4726.

With a weight of only 42 grams and compact dimensions (105 × 68 × 43 mm), it facilitates transport and installation even in limited technical spaces.
