Pre-Opened Constant Tension Bands are the ideal fasteners for hose-spigot connections which are subject to extreme temperature changes, or which tend to "slip away" under pressure of the clamp. This version is secured by a small plastic clip. After slipping the clamp onto the hose, this clip can be easily removed by hand. Pre-opened, (and if desired, pre-positioned on the hose) these spring band clamps are quick to assemble and easy to install. Their integrated spring retaining mechanism provides a continuously readjusting dynamic tightening effect. They are available in band widths of 12 and 15 mm and will accommodate nominal diameters from 13 up to 80 mm.

Features and Benefits

Features and Benefits

 N/A These clamps provide a quick, secure and maintenance-free connection for hoses that are exposed to large fluctuations in temperature. Even at low temperatures, the radially-acting tightening force is sufficient to assure a reliable tightness of the system. The additionally applied organic/inorganic coating provides the clamp with excellent anti-corrosion properties.
