Compression reducing coupling, polyethylene, PN 6 bar, d. 63 x 25

HDPE compression reducing coupling PN 6 bar, d 63 × 25 is a transition adapter designed to reliably connect Ø63 mm and Ø25 mm pipes without welding or special equipment. This format is commonly used when you need to branch/distribute flow from a larger-diameter main line to thinner runs (irrigation, on-site water distribution, equipment connections) while maintaining leak-tightness and stable system performance.

The fitting is made from high-quality high-density polyethylene (HDPE). The material is corrosion-free, withstands operational loads, and is well suited to systems where long service life matters. The inner surface of the connection is uniform and non-porous, allowing smooth flow while reducing the risk of deposits and channel “clogging.” The design contains no impurities that could affect the taste or odor of water—an important advantage for potable water supply and facilities with higher requirements for media cleanliness.

Joint reliability is ensured by several design features:

Rubber sealing rings provide strong leak resistance and are designed for PN 6 bar operation.

The conical tightening mechanism helps the joint seat evenly and compensates for minor pipe deviations in size and ovality up to ±0.5 mm. This is especially useful when installing pipes from different batches or under challenging site conditions.

A corrosion-resistant reinforcing ring improves long-term tightness and stability under temperature fluctuations, keeping the joint dense and reliable over extended service.

The fitting is also UV-resistant, making it suitable for outdoor pipeline sections, manholes, greenhouse systems, and irrigation lines. UV stability helps reduce the risk of algae and bacteria growth in sunlit parts of the system. The blue/black color supports quick visual identification and looks neat in assembled installations.

Compatibility: suitable for polyethylene and polyethylene terephthalate pipes.

Typical applications for the 63×25 PN 6 reducer:

potable and technical water supply networks;

irrigation/watering (Ø63 main line → Ø25 distribution);

industrial and domestic high-pressure sewer networks;

fire-fighting pipelines and auxiliary lines.

If you need a reliable 63×25 PN 6 HDPE compression reducer that installs quickly, holds tightness, and performs confidently under temperature swings and outdoor exposure, this fitting is a sensible choice for both installation and repair work.
