C-FLEX 0/1
Elastic Compensator
Rubber expansion joint with loose flanges that allows maximum flexibility during installation. The rubber bellows are made of EPDM to absorb axial, lateral and angular movements in low‑ to medium‑pressure systems. Its compact anti‑vibration design makes it ideal for water networks, HVAC systems, pump connections and rotating equipment.
✓ Nominal pressure: PN 2.5 to PN 16 bar; diameters DN 20 to DN 3,000 mm
✓ Full vibration absorption and noise damping in operation
✓ Special elastomers available (EPDM, Hypalon, Viton) depending on the fluid (water, air, light oils, foodstuffs)
C-FLEX 2
Elastic Compensator
Rubber expansion joint with fixed flanges. The rubber bellows are made of EPDM to absorb axial, lateral and angular movements in low‑ to medium‑pressure systems. Its compact anti‑vibration design makes it ideal for water networks, HVAC systems, pump connections and rotating equipment.
✓ Ideal for specific designs in industrial plants, drainage systems, and aerial ducts
✓ Full vibration absorption and noise damping in operation
✓ Flanges available in carbon steel, stainless steel or aluminium.
C-FLEX R
Double Corrugation Compensator
Rubber joint with double-wave configuration that allows maximum freedom of movement in all directions. Specially designed for flexible connections in systems with complex angular misalignments, multidirectional vibrations, and compact spaces.
✓ Multi-directional movement: axial, lateral, and angular simultaneously without restrictions
✓ Standard threaded connection (BSP, NPT, gas, flanges) adaptable to different configurations
✓ Maximum working pressure: 10 kgf/cm²; temperature range up to +90°C
