INDUSTRY-LEADING HYDRAULIC TENSIONING

Whatever the size, location, preload requirements, or application - our industry-leading tensioning technologies secure any bolted joint. With self-imposed quality standards above industry recommendations, which our tensioners get measured against in rigorous testing, you won’t find safer, more reliable tensioning.

Consistent and repeatable results for applications where accuracy is critical

Preload is very accurately controlled, as it is directly proportional to the pressure applied by the tensioner

Minimizes potential for uneven loading or gasket compression, which can occur with torque tightening methods

Industry leader in custom engineered solutions to suit any application
