Compression reducing coupling, polyethylene, PN 6 bar, d. 63 x 50

HDPE compression reducing coupling PN 6 bar, d 63 × 50 is a transition adapter designed to reliably connect Ø63 mm and Ø50 mm pipes without welding and without unnecessary time loss. This reducer is often required when assembling water supply and irrigation mains, when rehabilitating pipeline sections, or when you need a controlled step-down to a smaller diameter while maintaining system stability and ease of servicing.

The fitting is made from high-quality high-density polyethylene (HDPE), a material that performs exceptionally well in utility networks: it is strong, durable, and resistant to water exposure. The inner surface of the connection is uniform and non-porous, helping maintain even flow and reducing the likelihood of deposit build-up. The design contains no foreign substances that could affect the taste or odor of water, which makes it suitable for potable water systems and installations where media quality matters.

Joint tightness is ensured by multiple elements working together. Rubber sealing rings create a firm contact and provide strong leak resistance at the PN 6 bar working pressure. The conical tightening mechanism—one of the key features of compression fittings—compensates for minor pipe geometry deviations, including size differences and ovality up to ±0.5 mm. This is especially important in real-world installation conditions where pipes may come from different batches or have minimal tolerances. For added strength and long-term stability, a corrosion-resistant reinforcing ring is included to maintain tightness under temperature fluctuations and during extended service.

The fitting is also UV-resistant, making it suitable for outdoor pipeline sections, manholes, greenhouse systems, and irrigation networks where components may be exposed to sunlight. 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 easier on-site maintenance.

Compatibility: suitable for polyethylene and polyethylene terephthalate pipes.

Typical applications for the 63×50 PN 6 reducer:

potable and technical water supply networks;

irrigation and watering networks (Ø63 main line to Ø50);

industrial and domestic high-pressure sewer networks;

fire-fighting pipelines.

If you need a dependable 63×50 HDPE compression fitting that installs quickly, holds tightness, and is built for long service life, this PN 6 bar coupling is a practical solution for both professional installation and private projects.
