Flexible spiral, for cleaning jobs with short distances with a succession of pipe bends
- Self locking connection of spiral and coupling: With increased stress on the spiral, the torque pressure on the spiral end is increased and is transferred with 100% surface coverage onto the coupling
- Safety ring made out of flexible and self-binding material: With increased stress the ring will not slide, rather because of the 100% surface pressure, it adjusts itself to positively lock onto the coupling
- Optimum force transmission for professional pipe cleaning
- Increased safety
- Increased durability/service life of the spiral
