Compression reducing coupling, polyethylene, PN 6 bar, d. 32 x 25

HDPE compression reducing coupling PN 6 bar, d 32 × 25 is a transition fitting designed to quickly and tightly connect pipes of different diameters: Ø32 mm → Ø25 mm. It is a convenient solution for installation and repairs wherever welding needs to be avoided, time must be saved, and a reliable long-term joint is required.

The fitting is made of high-density polyethylene (HDPE) — a durable material that performs well in water environments and withstands external impacts. Its inner surface is uniform and non-porous, so water flows smoothly with minimal turbulence and reduced risk of deposits building up. The construction contains no substances that could affect the taste or smell of water, making it a strong choice for potable water networks and engineering systems related to food applications.

Tightness is ensured by rubber sealing rings that resist leakage at the PN 6 bar working pressure. The key benefit of the compression system is the conical tightening mechanism: it compensates for small pipe geometry deviations (size/ovality up to ±0.5 mm) and helps achieve a firm grip even in “field” conditions where pipes may come from different batches. An additional corrosion-resistant reinforcing ring improves long-term leak-tightness and stability during temperature fluctuations.

The fitting is UV-resistant, which is especially important for outdoor sections, manholes, irrigation systems, and pipelines exposed to sunlight. UV stability also helps reduce the risk of algae and bacteria growth in illuminated areas. The blue/black color makes on-site identification faster and easier.

Typical applications for the 32×25 PN 6 reducer:

main lines and branches for potable water supply;

irrigation, watering, and greenhouse systems;

industrial and domestic high-pressure sewer networks;

fire-fighting pipelines and technical water supply.

Customer benefits:

fast installation without welding or special equipment;

reliable leak protection thanks to sealing rings;

compensates pipe ovality up to ±0.5 mm;

durable, UV-resistant, and stable under temperature changes;

compatible with polyethylene and polyethylene terephthalate pipes.

If you need a compact, reliable, and “fail-safe” Ø32 to Ø25 reducer for stable system performance, this coupling is an excellent choice.
