Compression reducing coupling, polyethylene, PN 6 bar, d. 110 x 63

HDPE compression reducing coupling PN 6 bar, d 110 × 63 is a heavy-duty transition adapter for main pipelines when you need to step down from Ø110 mm to Ø63 mm without welding and without unnecessary downtime. This fitting is especially востребован in water supply and irrigation projects: the large-diameter main remains the “backbone,” while Ø63 becomes a convenient distribution line—to irrigation zones, pumping equipment, on-site distribution, or individual consumption points.

The body is made from high-quality high-density polyethylene (HDPE). The material is moisture-resistant, does not rust, and is designed for long-term service in utility networks. The inner surface of the connection is uniform and non-porous, which stabilizes flow, reduces the risk of deposit build-up, and keeps system hydraulics predictable. This also matters for potable water: the product contains no foreign substances that could affect taste or odor, so the reducer is suitable for drinking water lines and food-related circuits.

Connection reliability comes from a set of design features that “protect” installation against typical issues:

Rubber sealing rings provide strong leak resistance and confident operation at PN 6 bar.

The conical tightening mechanism compensates for minor pipe geometry deviations—size differences and ovality up to ±0.5 mm—so the fitting performs well even on real construction sites where pipes may come from different batches or have minimal tolerances.

A corrosion-resistant reinforcing ring strengthens the joint and helps maintain long-term tightness under temperature fluctuations, keeping the connection stable throughout its service life.

Another practical advantage is UV resistance. The fitting is suitable for outdoor routes, manholes, chambers, greenhouse installations, and irrigation systems where components may be exposed to sunlight. UV stability also helps reduce the risk of algae and bacteria growth in sunlit sections. The blue/black color makes the connection easy to spot and identify during maintenance.

Compatibility: suitable for polyethylene and polyethylene terephthalate pipes.

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

If you need a reliable 110×63 PN 6 HDPE reducer that installs quickly, holds tightness, and is built for long service life, this compression coupling is a practical solution for professional installation and operation.
