Compression reducing coupling, polyethylene, PN 6 bar, d. 110 x 75

HDPE compression reducing coupling PN 6 bar, d 110 × 75 is a reliable fitting for a fast transition from a Ø110 mm main pipe to a Ø75 mm line. This reducer is commonly used in distribution nodes: when the primary line is built with extra flow capacity and you need to step down to a smaller working branch for on-site distribution, irrigation zones, technical lines, or equipment connections. The key advantage is welding-free installation—fast, clean, and with predictable leak-tightness.

The fitting is made from high-quality high-density polyethylene (HDPE). The material is corrosion-free, handles operational loads well, and is suitable for long-term use in pipeline systems. Its inner surface is uniform and non-porous, so flow remains stable, deposit build-up is reduced, and system hydraulics stay consistent for longer. The design contains no foreign substances that could affect the taste or odor of water, making it suitable for potable water networks and engineering circuits where media cleanliness matters.

Leak-tightness of the 110×75 transition is ensured by several elements:

Rubber sealing rings create a tight contact and provide strong leak resistance at PN 6 bar working pressure.

The conical tightening mechanism—one of the key features of compression fittings—addresses typical pipe imperfections related to minor size differences and ovality up to ±0.5 mm. This is especially useful on site when pipes may vary by batch or storage conditions, helping you achieve a tight joint “from the first try.”

A corrosion-resistant reinforcing ring strengthens the joint and ensures long-term tightness under temperature fluctuations, increasing overall service life.

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

Compatibility: suitable for polyethylene and polyethylene terephthalate pipes.

Applications: potable and technical water supply, irrigation and watering networks, industrial and domestic high-pressure sewer networks, fire-fighting pipelines.

If you are looking for a dependable 110×75 PN 6 HDPE compression reducer that installs quickly, holds tightness, and is built for long service life across different conditions, this coupling is a practical choice for professional installation and operation.
