Advantages of Dual Hydraulic Ports
Hydraulic Tensioning Information Tensioning FAQ Advantages of dual hydraulic ports

Why do the Hydraulic Stud Tensioners Have Dual Hydraulic Ports?

Most of HTI’s Hydraulic Stud Tensioners have Dual Hydraulic Ports, even though they are single-acting because Dual Ports simplify the Hydraulic Hose connections. Typically, a longer Hose (15’ or 5m) connects from the Hydraulic Pump to the first Tensioner. Additional Hydraulic Hoses interconnect the Hydraulic Stud Tensioners in series, or “daisy-chained”.

Hydraulic Hoses have rated working pressures consistent with the working pressure of the Hydraulic Stud Tensioner and are available at any length. They are supplied with Hydraulic Quick-Disconnect (QD) Fittings and are pre-charged with hydraulic oil.

Would I ever need a single port?

For some applications, it is more convenient or faster to connect the Tensioner in parallel. In these cases, HTI can supply the Hydraulic Stud Tensioner with a single port and QD fitting. The Tensioners are interconnected using either Hydraulic Hoses with Tees, for series connection, or with a distribution block for parallel connection.
