Reducing coupling blackline Plastica Alfa

Reducing coupling

SKU: 13820 Categories: , , ,

The Reducing Compression Coupling of the Black line series is ideal for connecting Polyethylene pipes (PELD, PEMD and PEHD) and PPR pipes of different diameters in the distribution of pressurised fluids in irrigation and water systems. The coupling is designed and tested to guarantee a PN16 working pressure.

The Reducing Coupling is used in drinking water conveyance systems in aqueducts and civil installations, in irrigation and gardening, fire-fighting systems, geothermal systems, waste and industrial water conveyance and compressed air systems.

REINFORCING RING:

*Optional reinforcement ring*

The presence of the reinforcement ring in couplings with female threads provides an additional guarantee in terms of resistance to operating pressures, especially at high temperatures and in the long term.
