hose protection spiral
Does your hose wear unevenly? Is the dragged on hard surfaces? Do your hoses get lots of strikes?
Safe-Spiral Abra is 2-coloured wear indicator spiral.
Safe-Spiral Abra helps you to identify those difficult spots that need more careful observation: once the black top layer wears off and you can see the yellow colour, you know the spiral needs to be replaced soon.
Abrasion of this spiral is very minimal, even though the thickness of the top layer is only 0.5mm. It would take approximately 1000km or 415 hours to wear off, at 1.9 MPa surface pressure (pin-on-disk tester).
