Application: connecting and repairing pipes made of steel, GRP, cast iron, plastic or asbestos.
Arpol flexible couplings are used to join and repair pipes of all common materials. Couplings are suitable for pressure and gravity lines containing most types of fluids.
Arpol system provides secure and durable sealing, even on rough surfaces.
Flexible couplings can be applies in water distribution systems, water treatment, industry, power stations, construction and domestic installations, shipbuilding.
