Corrosion resistant and reliable TUV approved high precision single ear stepless hose clamps are made of 304 stainless steel. They resist rust and corrosion for long-term use and are a good choice for sealing various hoses. The kit includes a pincer to increase clamp force, and the jaws of the crimper are made of chrome vanadium steel, durable and will not collapse or deform. This is a practical design for repairing pipes and plumbing systems. Cochlear design for constant seal Cochlear design ensures continuous clamping during temperature changes, machine variations, or dimensional changes. The pipe remains in a good sealing and fastening status. Polished smooth edge and precise seal The edge of all clamps is polished smooth to avoid hose damage. 360° stepless design provides no inner protrusion or gap, and the narrow band design delivers a more centralized seal pressure.
