Single vs. Twin Couplings
Hydraulic tensioning with hydraulic tensioners and nuts is the ideal method for tightening bolted connections. Hydraulic tensioning eliminates inaccuracies and helps achieve correct bolt loading in critical fasteners. At HTI, we’ve been building hydraulic tensioners and nuts since 1986.
Most hydraulic nut tensioning applications involve multiple nuts tensioned simultaneously. Twin hydraulic ports allow the chaining of nuts together for use with a single hydraulic pressure source.
We also offer nuts with a single hydraulic coupling that can be used in isolation.
As an alternative to a single port, HTI provides a port cap (typically used to cap the second port in the last nut in a chained nut system) that can be used in place of the second port, for stand-alone nut use.
Custom Engineered Solutions Since 1986
HTI has been designing engineered solutions to your toughest bolt tensioning problems for over 35 years! Choose from one of HTI’s hydraulic nut catalog models or we can design a custom hydraulic nut for any application when a standard model won’t work. HTI hydraulic nuts can be designed for imperial or metric-sized studs. Contact us to start the process of getting the right tensioning solution for your application.
