Compression reducing coupling, polyethylene, PN 6 bar, d. 50 x 25

HDPE compression reducing coupling PN 6 bar, d 50 × 25 is a transition adapter that securely connects a Ø50 mm main line to a Ø25 mm line while maintaining leak-tightness and stable system operation. It is a practical choice for projects where flow needs to be “distributed” from a main pipe into thinner branches (irrigation, on-site distribution, equipment connections), and installation must be completed quickly—without welding or specialized equipment.

The fitting is made of high-density polyethylene (HDPE), a material with a proven track record in pipeline systems. Inside the coupling, the surface is uniform and non-porous, which reduces the likelihood of deposits and lowers hydraulic resistance. For water supply, this is also important in terms of quality: the product contains no components that could affect the taste or odor of water, making it suitable for potable water networks and engineering systems related to food applications.

Joint reliability is achieved through a combination of design features. First, rubber sealing rings provide strong resistance to leaks and are designed for PN 6 bar operation. Second, the conical tightening mechanism helps address typical “field” installation issues: it compensates for size differences and pipe ovality up to ±0.5 mm, so the connection remains secure even with minor geometry deviations. Third, a corrosion-resistant reinforcing ring improves long-term tightness and stability under temperature fluctuations, ensuring the joint stays dense and reliable throughout its service life.

An additional benefit is UV resistance. The fitting is suitable for outdoor pipeline sections, manholes, greenhouse systems, and irrigation lines where components may be exposed to sunlight. UV stability helps reduce the risk of algae and bacteria growth in sunlit sections. The blue/black color makes identification easier and provides a neat look in assembled systems.

Compatibility: suitable for polyethylene and polyethylene terephthalate pipes.

Typical applications for the 50×25 reducer:

potable and technical water supply for private homes and facilities;

irrigation/watering (Ø50 main line → distribution into Ø25);

industrial and domestic high-pressure sewer networks;

fire-fighting pipelines.

If you need a reliable 50×25 PN 6 HDPE compression fitting that installs fast, holds tightness, and “forgives” minor pipe deviations, this coupling is an excellent choice for installation and repair work.
