12.7mm Perforated Hose Clamp
Wide steel band ensures uniform pressure distribution over the hose around which the perforated hose clamp is tightened. Highly praised for accurate, secure hose clamping, the 12.7mm perforated hose clamp can be reconfigured to a different band width, such as 14.2mm.
Advantages of Perforated Hose Clamp
Adjustable screw, paired with perforated steel stand with rectangular slots on it, delivers a large tightening torque and secure hose clamping. By adjusting the length of steel band, it is easy to strap large parts on bulky equipment. The screw band clamp is suitable for fastening square and cylindrical objects such as flue pipes and batteries, delivering unparalleled clamping performance.
