Repair coupling

The Blu line Plus series compression repair coupling is ideal for connecting and repairing polyethylene pipes (PELD, PEMD and PEHD) and PPR pipes in the distribution of pressurised fluids in irrigation and waterworks systems. The coupling does not require complete disassembly (push-in) and is designed and tested to guarantee a PN16 working pressure.

It is similar to a coupling sleeve but, unlike the latter, does not have a knocker inside it; this allows the coupling sleeve to slide through the pipe and thus enables rapid repair of polyethylene pipes. They can be used where the working conditions are complex, whether in drinking water transport systems in aqueducts and civil installations, irrigation and gardening, fire-fighting systems, geothermal systems, sewage 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.
