Spiral hose suitable for underground pressurized systems in swimming pools and hot tubs. Plasticized PVC hose structured with a rigid PVC reinforcement spiral (D-Shape patent) against crushing. The spiral is coated with a special film (Spiral Protection Barrier patent) which gives the hose anti-cracking properties. Made of special material, the film (Chlorine Defence System patent) is placed internally to protect the hose from chlorine and the resulting acid environment. Externally calibrated for perfect bonding with glued and compressed fittings.
In compliance with the European Regulation Reg. (EU) 10/2011 for simulants A.
The spiral with D-Shape cross-section is extremely resistant to crushing (up to 34 kN/m2). Combined with the use of premium materials, it guarantees high flexibility and a smaller radius of curvature (up to 125 mm).
The lining of the rigid spiral (Spiral Protection Barrier) acts as a barrier that prevents premature embrittlement due to environmental stress cracking (ESC).
The CDS (Chlorine Defence System) film offers extensive protection even against high-chlorine water and acidic environments, guaranteeing lasting performance.
In compliance with the European Regulation Reg. (EU) 10/2011 for simulants A. Performance tests (mechanical and chemical) were done both internally and in collaboration with University of Padua – DTG Laboratory. Test certified by TÜV (test report No. MEC16173.00).
