Hydraulic Tensioner

In order to derive 100% of the performance of gland packing, it is
most important to perform surface pressure transmission uniformly .
In the case of vaulting with a spanner, skilled skill is required, but by using a hydraulic tensioner it is possible to tighten the workpiece, which is inexperienced, relatively easily and uniformly and reliably transmits surface pressure, Sealing performance can be easily drawn out.
