Narrow band design: more concentrated clamping force, lighter weight and less interference360 stepless design: the surface of the hose is compressed evenly, and the 360 seal ensures ear width: the deformation size can compensate for the hose hardware tolerance and adjust the surface pressure to control the clamping effect.Cochlear design: provides a powerful thermal expansion compensation function, so that the dimensional changes of the hose caused by temperature changes are compensated, so that the pipe fittings are always in a good sealed and tightened state.Smooth inner band and uniform compression Suitable for demanding applications where lighter, thin-walled hose or tubing is being usedSpecial process treatment: avoid damage to hoses and safety of work equipmentColour:Red & SilverMaterial:stainless steelSize:20pcs 6-7mm20pcs 7-8.7mm20pcs 8.8-10.5 mm20pcs 10.3-12.8 mm20pcs 12.8-15.3 mm15pcs 15.3-18.5mm15pcs 17.8-21mmPackage Contents:130 * Ear Stepless Hose Clamp with plierOnly the above package content, other products are not included.Note: Light reflection and different displays may cause the color of the item in the picture a little different from the real thing.
